Description
Demonstration circuit 1774A-A is a differential ADC
driver/IF amplifier featuring the LTC®6430-15. It is part
of the DC1774A demo board family supporting the
LTC643X-YY amplifier series. The DC1774A-A is optimized for a frequency range of 100MHz to 300MHz and
utilizes a minimum of passive external components to
configure the amplifier for this application.
Performance Summary
SYMBOL
Because the LTC6430-15 has 100Ω differential input and
output impedance, the demo circuit uses transformers to
convert the impedance to 50Ω single-ended allowing easy
evaluation with commercially available RF test equipment.

Demo Circuit 1774A-A is a highly linear fixed-gain amplifier. The LTC6430-15 is internally matched to a 100Ω
differential source and load impedance from 20MHz to
1300MHz. Due to the unpopularity of 100Ω differential
test equipment, transformers have been added to convert
impedance from differential 100Ω to single-ended 50Ω
for the input and the output ports. The frequency range
of the circuit is limited by the balun transformers. Hence,
this demo board works best with a frequency range from
100MHz to 300MHz. Figure 2 shows the performance of
the demo board.

Operation
Figure 3 shows the simplified demo circuit schematic. It
requires a minimum of passive supporting components.
The 2:1 transformers convert the differential to singleended 50Ω for compatibility with most test equipment.
The input and output DC-blocking capacitors (C1, C2,
C3 and C4) are required because this device is internally biased for optimal operation. The frequency appropriate choke (L1 and L2) and the decoupling capacitors (C5,
C21, C22 and C23) provide bias to the RF ±OUT nodes. Only
a single 5V supply is necessary for VCC pins on the device.
Table 1 shows the function of each input and output on
the board.
An optional input stability network has been added. It
consists of a parallel 62pF (C8 and C9) and 348Ω (R1
and R2) input network to insure low frequency stability.

Operation
Additional Information
prevent solder from wicking away from the critical PCB
to the exposed pad interface.
The particular element values shown in the demo board
schematic are chosen for wide bandwidth operation.
Depending on the desired frequency, performance may
be improved by the proper selection of these supporting
components.
The DC1774A-A has a nominal working frequency range
from 100MHz to 300MHz. It is not intended for operation
down to DC. The lower frequency cutoff is limited by onchip matching elements.
As with any RF device, minimizing ground inductance
is critical. Care should be taken with the board layout
because of these exposed pad packages. The maximum
number of minimum diameter vias holes should be placed
underneath the exposed pad. This will ensure good RF
ground and low thermal impedance. Maximizing the
copper ground plane will also improve heat spreading
and low inductance. It is a good idea to cover the via
holes with solder mask on the back side of the PCB to
Figure 6 shows the generic PCB schematic for the
LTC643X-YY amplifier series. The board can be modified for multiple demo board versions. For example,
both DC1774A-A and DC1774A-B demo boards have a
differential amplifier at U1, therefore, the board is using
transformers to transform from differential to singleended input and output. Likewise, the DC1774A-C is a
single-ended demo board; it uses the LTC6431-15 for
single-ended input and output.
Setup and Testing Signal Sources
The LTC6430-15 is an amplifier with high linearity performance, therefore output intermodulation products are
very low. For this reason, it drives most test equipment
and test setups to their limits. Consequently, accurate
measurement of the third-order intercept point for a low
distortion IC such as the LTC6430-15 requires certain
precautions to be observed in the test setup and testing
procedure.
Setup signal sources
Figure 5 shows a proposed IP3 test setup. This setup has
low phase noise, good reverse isolation, high dynamic
range, sufficient harmonic filtering and wideband impedance matching. The setup is outlined here:
a. High performance signal generators 1 and 2 (HP8644A)
should be used in the setup. These suggested generators have low harmonic distortion and very low phase
noise.
b. High linearity amplifiers to improve isolation. They
prevent the two signal generators from crosstalking
with each other and provide higher output power.
c. A lowpass filter to suppress harmonic contents from
interfering with the test signal.
d. The signal combiner (from Mini-Circuits, ADP-2-9)
combines the two isolated input signals. This combiner
has a typical isolation of 27dB. For better VSWR and
isolation, use the H-9 signal combiner from M/A-COM,
which features >40dB isolation and a wider frequency
range. Passive devices (e.g., combiners) with magnetic
elements can contribute nonlinearity to the signal chain
and should be used cautiously.
e. The attenuator pads, on all three ports of the signal
combiner, will support further isolation of the two input
signal sources. They will reduce reflection and promote
maximum power transfer with wideband impedance
matching.

DEMO MANUAL DC1774A-A
Setup and Testing Signal Sources
Testing signal sources
a. Apply two independent signals, f1 and f2, from signal
generator 1 and signal generator 2 at 240MHz and
241MHz while setting amplitude = –12dBm per tone
at the combined output.
d. In order to achieve a valid measurement result, the
test system must have lower distortion than the DUT
intermodulation. For example, to measure a 47dBm
OIP3, the measured intermodulation products will be
–90dBc below the –12dBm per tone input level and
the test system must have intermodulation products
approximately –96dBc or better. For best results, the
IMD or noise floor should be at least –100dBc before
connecting the DUT.
b. Connect the combined signal directly to the spectrum
analyzer (without the DUT).
Testing the DUT
The testing signal should be evaluated and optimized before
it is used for measurements. The following outlines the
necessary steps to achieve optimization:
c. Adjust the spectrum analyzer for the maximum possible
resolution of the intermodulation products amplitude
in dBc relative to the main tone power. A narrower
resolution bandwidth will take a longer time to sweep.
Optimize the dynamic range of the spectrum analyzer
by adjusting input attenuation.
First increase the spectrum analyzer input attenuation
(normally in steps of 5dB or 10dB). If the IMD product
levels decrease when the input attenuation is increased,
then the input power level was too high for the spectrum
analyzer to make a valid measurement. In other words,
the spectrum analyzer 1st mixer was overloaded and
producing its own IMD products. If the IMD reading
holds constant with increased input attenuation, then
a sufficient amount of attenuation was present. Adding
too much attenuation will raise the noise floor and bury
the intended IMD signal. Therefore, select just enough
attenuation to achieve a stable and valid measurement.
At this point, the input level has been established at
–12dBm per tone, and the input IMD from the test setup
is well suppressed at –96dBm max. Furthermore, the
spectrum analyzer is set up to measure very low level
IMD components.
a. Insert the DUT and output attenuator into the setup,
inline between the signal source and the spectrum
analyzer. The output attenuator should match the DUT
gain.
b. Fine tune the signal generator levels by a small amount
if necessary (<1dB), to keep output power at 2dBm per
tone at the amplifier output.
c. Measure the output IMD level using the same optimized
setup as previous. Based on the output power level of
2dBm per tone, and knowing the IMD level, OIP3 can
be calculated.

Quick Start Procedure
Demo Circuit 1774A-A can be set up to evaluate the performance of the LTC6430-15. Refer to Figures 4 and 5 for
proper equipment connections and follow this procedure:
Single-Tone Measurement:
1. The power labels of +5V and GND directly correspond
to the power supply. Typical current consumption of
the LTC6430-15 is about 160mA.
2. Apply an input signal to J7. A low distortion, low noise
signal source with an external high order lowpass filter
will yield the best performance. The input signal is
–10dBm. The input is impedance-matched to 50Ω .
3. Observe the output via J8. The measured power at
the analyzer should be about 4dBm. The output is
impedance-matched to 50Ω, suitable for the input of
a network or spectrum analyzer.
Two-Tone Measurement:
Connect all test equipment as suggested in Figure 8.
1. The power labels of +5V and GND directly correspond
to the power supply. Typical current consumption of
the LTC6430-15 is about 160mA.
2. Apply two independent signals, f1 and f2, from SG1
and SG2, at 240MHz and 241MHz, respectively.
