DESCRIPTION
The TRF3701 is an ultralow-noise direct quadrature modulator that is capable of converting complex input
signals from baseband or IF directly up to RF. An internal analog combiner sums the real and imaginary
components of the RF outputs. This combined output can feed the RF preamp directly at frequencies of up to
1.5 GHz. The modulator is implemented as a double-balanced mixer. An internal local oscillator (LO) phase
splitter accommodates a single-ended LO input, eliminating the need for a costly external balun.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be
more susceptible to damage because very small parametric changes could cause the device not to meet its published
specifications.

DEFINITIONS OF SELECTED SPECIFICATIONS
Unadjusted Carrier Suppression
This specification measures the amount by which the local oscillator component is attenuated in the output
spectrum of the modulator relative to the carrier. It is assumed that the baseband inputs delivered to the pins of
the TRF3701 are perfectly matched to have the same dc offset (VCM). This includes all four baseband inputs:
IVIN, QVIN, IREF and QREF. Unadjusted carrier suppression is measured in dBc.
Adjusted (Optimized) Carrier Suppression
This differs from the unadjusted suppression number in that the dc offsets of the baseband inputs are iteratively
adjusted around their theoretical value of VCM in order to yield the maximum suppression of the LO component
in the output spectrum. Adjusted carrier suppression is measured in dBc.
Unadjusted Sideband Suppression
This specification measures the amount by which the unwanted sideband of the input signal is attenuated in the
output of the modulator, relative to the wanted sideband. It is assumed that the baseband inputs delivered to the
modulator input pins are perfectly matched in amplitude and are exactly 90° out of phase. Unadjusted sideband
suppression is measured in dBc.
Adjusted (Optimized) Sideband Suppression
This differs from the unadjusted sideband suppression in that the baseband inputs are iteratively adjusted
around their theoretical values to maximize the amount of sideband suppression. Adjusted sideband
suppression is measured in dBc.
Suppressions Over Temperature
This specification assumes that the user has gone through the optimization process for the suppression in
question, and set the optimal settings for the I, Q inputs at room temperature. This specification then measures
the suppression when temperature conditions change after the initial calibration is done.

THEORY OF OPERATION
The TRF3701 employs a double-balanced mixer architecture in implementing the direct I, Q upconversion. The I,
Q inputs can be driven single-endedly or differentially, with comparable performance in both cases. The common
mode level (VCM) of the four inputs (IVIN, IREF, QVIN, QREF) is typically set to 3.7 V and needs to be driven
externally. These inputs go through a set of differential amplifiers and through a V-I converter feed the
double-balanced mixers. The AC-coupled LO input to the device goes through a phase splitter to provide the
in-phase and quadrature signals that in turn drive the mixers. The outputs of the mixers are then summed,
converted to single-ended signals, and amplified before they are fed to the output port RFOUT. The output of
the TRF3701 is ac-coupled and can drive 50-Ω loads.

APPLICATION INFORMATION
DRIVING THE I, Q INPUTS
There are several ways to drive the four baseband inputs of the TRF3701 to the required amplitude and dc
offset. The optimal configuration depends on the end application requirements and the signal levels desired by
the designer.
The TRF3701 is by design a differential part, meaning that ideally the user should provide fully complementary
signals. However, similar performance in every respect can be achieved if the user only has single-ended
signals available. In this case, the IREF and QREF pins just need to have the VCM dc offset applied.
Implementing a Single-to-Differential Conversion for the I, Q inputs
In case differential I, Q signals are desired but not available, the THS4503 family of wideband, low-distortion,
fully differential amplifiers can be used to provide a convenient way of performing this conversion. Even if
differential signals are available, the THS4503 can provide gain in case a higher voltage swing is required.
Besides featuring high bandwidth and high linearity, the THS4503 also provides a convenient way of applying
the VCM to all four inputs to the modulator through the VOCM pin (pin 2). The user can further adjust the dc
levels for optimum carrier suppression by injecting extra dc at the inputs to the operational amplifier, or by
individually adding it to the four outputs. Figure 55 shows a typical implementation of the THS4503 as a driver
for the TRF3701. Gain can be easily incorporated in the loop by adjusting the feedback resistors appropriately.
For more details, see the THS4503 data sheet at www.ti.com.

DRIVING THE LOCAL OSCILLATOR INPUT
The LO pin is internally terminated to 50 Ω, thus enabling easy interface to the LO source without the need for
external impedance matching. The power level of the LO signal should be in the range of –6 to 6 dBm. For
characterization purposes, a power level of 0 dBm was chosen. An ideal way of driving the LO input of the
TRF3701 is by using the TRF3750, an ultralow-phase-noise integer-N PLL from Texas Instruments. Combining

the TRF3750 with an external VCO can complete the loop and provide a flexible, convenient and cost-effective
solution for the local oscillator of the transmitter. Figure 56 shows a typical application for the LO driver network
that incorporates the TRF3750 integer-N PLL synthesizer into the design. Depending on the VCO output and the
amount of signal loss, an optional gain stage may be added to the output of the VCO before it is applied to the
TRF3701 LO input.

Figure 56. Typical Application Circuit for Generating the LO Signal for the TRF3701 Modulator
PCB LAYOUT CONSIDERATIONS
The TRF3701 is a high-performance RF device; hence, care should be taken in the layout of the PCB in order to
ensure optimum performance. Proper decoupling with low ESR capacitors is needed for the VCC supplies (pins
6 and 10). Typical values used are in the order of 1 pF in parallel to 0.1 µF, with the lower-valued capacitors
placed closer to the device pins. In addition, a larger tank capacitor in the order of 10 µF should be placed on
the supply line as layout permits. At least a 4-layer board is recommended for the PCB. If possible, a solid
ground plane and a ground pour is also recommended, as is a power plane for the supplies. Because the
balance of the four I, Q inputs to the modulator can be critical to device performance, care should be taken to
ensure that the trace runs for all four inputs are equidistant. In the case of single-ended drive of the I, Q inputs,
the two unused pins IREF and QREF are fed with the VCM dc voltage only, and should be decoupled with a
0.1-µF capacitor (or smaller). The LO input trace should be minimized in length and have controlled impedance
of 50 Ω. No external matching components are needed because there is an internal 50-Ω termination. The
RFOUT pin should also have a relatively small trace to minimize parasitics and coupling, and should also be
controlled to 50 Ω. An impedance-matching network can be used to optimize power transfer, but is not critical.
All the results shown in the data sheet were taken with no impedance matching network used (RFOUT directly
driving an external 50-Ω load).
The exposed thermal and ground pad on the bottom of the TRF3701 should be soldered to ground to ensure
optimum electrical and thermal performance. The landing pattern on the PCB should include a solid pad and 4
thermal vias. These vias typically have 1,2-mm pitch and 0,3-mm diameter. The vias can be arranged in a 2×2
array. The thermal pad on the PCB should be at least 1.65×1.65 mm.
IMPLEMENTING A DIRECT UPCONVERSION TRANSMITTER USING A TI CommsDAC
The TRF3701 is ideal for implementing a direct upconversion transmitter, where the input I, Q data can originate
from an ASIC or a DAC. Texas Instruments' line of digital-to-analog converters (DAC) is ideally suited for
interfacing to the TRF3701. Such DACs include, among others, the DAC290x series, DAC5672, and DAC5686.

APPLICATION INFORMATION (continued)
This section illustrates the use of the DAC5686, which offers a unique set of features that make interfacing to
the TRF3701 easy and convenient. The DAC5686 is a 16-bit, 500 MSPS, 2×–16× interpolating dual-channel
DAC, and it features I, Q adjustments for optimal interface to the TRF3701. User-selectable, 11-bit offset and
12-bit gain adjustments can optimize the carrier and sideband suppression of the modulator, resulting in
enhanced performance and relaxed filtering requirements at RF. The preferred mode of operation of the
DAC5686 for direct interface with the TRF3701 at baseband is the dual-DAC mode. The user also has the
flexibility of selecting any one of the four possible complex spectral bands to be fed into the TRF3701. For
details on the available modes and programming, see the DAC5686 data sheet available at www.ti.com.
Figure 57 shows the DAC5686 in dual-DAC mode, which is best-suited for zero-IF interface to the TRF3701. In
this mode, a seamless, passive interface between the DAC output and the input to the modulator is used, so
that no extra components are needed between the two devices. The optimum dc offset level for the inputs to the
TRF3701 (VCM) is approximately 3.7 V. The output of the DAC should be centered around 3.3 V or less
(depending on signal swing), in order to ensure that its output compliance limits are not exceeded. The resistive
network shown in Figure 57 allows for this dc offset transition while still providing a dc path between the DAC
output and the modulator. This ensures that the dc offset adjustments on the DAC5686 can still be applied to
optimize the carrier suppression at the modulator output. The combination of the DAC5686 and the TRF3701

APPLICATION INFORMATION (continued)
TRF3701 Power Down (PWD) Pin Operation
The power down pin (PWD) in the TRF3701 powers down the chip when 0V is applied to this pin. The TRF3701
is enabled when 5V is applied to the PWD pin. Figure 58 shows the output power as a function of time when the
PWD pin is pulled down from 5V to 0V. Both the I/Q signals and the LO are present during the power down.
Figure 59 shows the output power as a function of time when the PWD pin is pulled up from 0V to 5V. In both
the power down and power up operation there is a smooth transition with no glitches in output power.
The device will not turn on till a voltage greater than 1.2V is applied at the PWD pin. In addition the device does
not turn off till the PWD is pulled below 3.7V. This ensures that the device does not accidentally change state
due to glitches on the PWD pin. The turn on time of the device is 120 ns and the turn off time is 20 ns.
