1700MHz to 3000MHz High-Linearity,
Low LO Leakage Base-Station Rx/Tx Mixer
Features
The MAX2043 high-linearity passive upconverter or
downconverter mixer is designed to provide approximately +31dBm of IIP3, +67dBc of LO ± 2IF spurious
rejection, 7.8dB of noise figure, 7.5dB of conversion
loss, and -52dBm of LO leakage for UMTS/WCDMA,
DCS, PCS, and WiMAX base-station applications. With
a 1700MHz to 3000MHz RF frequency range and a
1900MHz to 3000MHz LO frequency range, this mixer
is ideal for high-side LO injection architectures.
In addition to offering excellent linearity and noise performance, the MAX2043 also yields a high level of component integration. The MAX2043 integrates baluns in
the RF and LO ports, a dual-input LO-selectable switch,
an LO buffer, and a double-balanced mixer. The onchip baluns allow for a single-ended RF input for downconversion (or RF output for upconversion), and
single-ended LO inputs. The MAX2043 requires a typical 0dBm LO drive, and supply current is rated at a typical 108mA level. The IF port is DC-coupled, making it
ideal for direct conversion or modulation. As an upconverter, the device has low output noise floor of less than
-160dBc/Hz (-160dBm/Hz when transmitting 0dBm linear RF power).
♦ +31dBm Typical 3rd-Order Input Intercept Point
The MAX2043 is available in a 36-pin thin QFN package (6mm x 6mm) with an exposed paddle. Electrical
performance is guaranteed over the extended -40°C to
+85°C temperature range.

Note 1: All limits reflect losses of external components. Output measurement taken at IF port of Typical Application Circuit.
Note 2: The lower IF frequency limit of 0MHz is limited by the external IF transformer.
Note 3: Measured with external LO source noise filtered so its noise floor is not a contributor. Measured with: fRF = 2000MHz,
fBLOCKER = 2100MHz, fLO = 2190MHz, using a 190MHz SAW filter on the IF port. This specification reflects the effects of
all SNR degradations in the mixer, including the LO noise as defined in Maxim Application Note 2021.
Note 4: Maximum reliable continuous input power applied to the RF or IF port of this device is +15dBm from a 50Ω source.
Note 5: Typical Operating Characteristics show LO drive extended to +6dBm
Note 6: Measured IF port at IF frequency. fLO1 and fLO2 are offset by 1MHz.
Note 7: IF return loss can be optimized by external matching components.

Detailed Description
The MAX2043 can operate as either a downconverter
or an upconverter mixer that provides 7.5dB of conversion loss with a typical 7.8dB noise figure. IIP3 is
+31dBm for both upconversion and downconversion.
The integrated baluns and matching circuitry allow for
50Ω single-ended interfaces to the RF port and two LO
ports. The RF port can be used as an input for downconversion or an output for upconversion. A singlepole, double-throw (SPDT) switch provides 50ns
switching time between the two LO inputs with 43dB of
LO-to-LO isolation and -52dBm of LO leakage.
Furthermore, the integrated LO buffer provides a high
drive level to the mixer core, reducing the LO drive
required at the MAX2043’s inputs to a -3dBm to +6dBm
range. The IF port incorporates a differential output for
downconversion, which is ideal for providing enhanced
IIP2 performance. For upconversion, the IF port is a differential input.
Specifications are guaranteed over broad frequency
ranges to allow for use in UMTS/WCDMA and
2G/2.5G/3G DCS 1800, PCS 1900, cdma2000, and
WiMAX base stations. The MAX2043 is specified to
operate over a 1700MHz to 3000MHz RF input range, a
1900MHz to 3000MHz LO range, and an IF range of
near 0MHz to 350MHz. The external IF component sets
the lower frequency range.
12
RF Port and Balun
For using the MAX2043 as a downconverter, the RF
input is internally matched to 50Ω, requiring no external
matching components. A DC-blocking capacitor is
required because the input is internally DC shorted to
ground through the on-chip balun. The RF return loss is
typically 15dB over the entire 1700MHz to 3000MHz RF
frequency range. For upconverter operation, the RF
port is a single-ended output similarly matched to 50Ω.
An optional L-C BPF can be installed at the RF port to
improve some upconverter performance.
LO Inputs, Buffer, and Balun
The MAX2043 is optimized for a 1900MHz to 3000MHz
LO range. As an added feature, the MAX2043 includes
an internal LO SPDT switch that can be used for frequency-hopping applications. The switch selects one
of the two single-ended LO ports, allowing the external
oscillator to settle on a particular frequency before it is
switched in. LO switching time is typically less than
50ns, which is more than adequate for typical GSM
applications. If frequency-hopping is not employed,
simply set the switch to either of the LO inputs. The
switch is controlled by a digital input (LOSEL): logichigh selects LO1, logic-low selects LO2. LO1 and LO2
inputs are internally matched to 50Ω, requiring only a
22pF DC-blocking capacitor. To avoid damage to the
______________________________________________________________________________________
1700MHz to 3000MHz High-Linearity,
Low LO Leakage Base-Station Rx/Tx Mixer
A two-stage internal LO buffer allows a wide input
power range for the LO drive. All guaranteed specifications are for an LO signal power from -3dBm to +6dBm.
The on-chip low-loss balun along with an LO buffer drives the double-balanced mixer. All interfacing and
matching components from the LO inputs to the IF outputs are integrated on-chip.
High-Linearity Mixer
The core of the MAX2043 is a double-balanced, high-performance passive mixer. Exceptional linearity is provided
by the large LO swing from the on-chip LO buffer.
Differential IF
Bias Resistor
Bias current for the on-chip LO buffer is optimized by
fine-tuning the off-chip resistor on pin 17 (R1). The current in the buffer amplifier can be reduced by raising
the value of this resistor but performance (especially IP3)
degrades. Doubling the value of this resistor reduces the
current in the device by approximately half.
Additional Tuning Components
The MAX2043 mixer performance can be further
enhanced with the use of external components. The
values of these components depend on the application
and the frequency band of interest. Consult the factory
for further details.
Layout Considerations
The MAX2043 mixer has a DC to 350MHz IF frequency
range where the low-end frequency depends on the
frequency response of the external IF components.
Note that these differential ports are ideal for providing
enhanced IIP2 performance. Single-ended IF applications require a 1:1 balun to transform the 50Ω differential IF impedance to 50Ω single-ended system. After the
balun, the IF return loss is better than 20dB. The user
can use a differential IF amplifier on the mixer IF ports,
but a DC block is required on both IF+ and IF- ports to
keep external DC from entering the IF ports of the
mixer. The mixer requires a DC ground return on either
the RF tap pin (short tap to ground) or on each IF differential port (1kΩ resistor or an inductor from each IF differential pin to ground).
A properly designed PC board is an essential part of
any RF/microwave circuit. Keep RF signal lines as short
as possible to reduce losses, radiation, and inductance. For the best performance, route the ground pin
traces directly to the exposed pad under the package.
The PC board exposed pad MUST be connected to the
ground plane of the PC board. It is suggested that multiple vias be used to connect this pad to the lower-level
ground planes. This method provides a good RF/thermal conduction path for the device. Solder the exposed
pad on the bottom of the device package to the PC
board. The MAX2043 evaluation kit can be used as a
reference for board layout. Gerber files are available
upon request at www.maxim-ic.com.
Applications Information
Proper voltage supply bypassing is essential for highfrequency circuit stability. Bypass each V CC pin and
TAP with the capacitors shown in the Typical
Application Circuit. See Table 1. Place the TAP bypass
capacitor to ground within 100 mils of the TAP pin.
Input and Output Matching
The RF and LO inputs are internally matched to 50Ω.
No matching components are required. Return loss at
the RF port is typically 17dB and return loss at the LO
ports are typically 14dB. RF and LO inputs require only
DC-blocking capacitors for interfacing.
The IF output impedance is 50Ω (differential). For evaluation, an external low-loss 1:1 (impedance ratio) balun
transforms this impedance to a 50Ω single-ended output (see the Typical Application Circuit).
Power-Supply Bypassing
Exposed Pad RF/Thermal Considerations
The exposed paddle (EP) of the MAX2043’s 36-pin thin
QFN-EP package provides a low thermal-resistance
path to the die. It is important that the PC board on
which the MAX2043 is mounted be designed to conduct heat from the EP. In addition, provide the EP with a
low-inductance path to electrical ground. The EP MUST
be soldered to a ground plane on the PC board, either
directly or through an array of plated via holes.
