MAX2043 Evaluation Kit
Quick Start
The MAX2043 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setupsection for proper device evaluation.
Test Equipment Required
This section lists the recommended test equipment to
verify the operation of the MAX2043. It is intended as a
guide only, and substitutions may be possible:DC supply capable of delivering +5.0V and 175mAThree RF signal generators capable of delivering
10dBm of output power in the 1GHz to 3GHz frequency
range (i.e., HP 8648)RF spectrum analyzer with a minimum 100kHz to
3GHz frequency range (HP 8561E)RF power meter (HP 437B)Power sensor (HP 8482A)
Connections and Setup
This section provides a step-by-step guide to testing
the basic functionality of the EV kit. As a general pre-
caution to prevent damaging the outputs by driving
high-VSWR loads, do not turn on DC power or RF signal
generators until all connections are made.
This procedure is specific to operation in the US PCS
band (reverse channel: 1850MHz to 1910MHz), high-
side injected LO for a 200MHz IF. Choose the test fre-
quency based on the particular system’s frequency
plan, and adjust the following procedure accordingly.
See Figure 1 for the mixer test setup diagram:Calibrate the power meter for 2100MHz. For safety
margin, use a power sensor rated to at least
+20dBm, or use padding to protect the power head
as necessary.Connect 3dB pads to DUT ends of each of the two
RF signal generators’ SMA cables. This padding
improves VSWR and reduces the errors due to mis-
match.Use the power meter to set the RF signal generators
according to the following:RF signal source: 0dBm into DUT at 1900MHz
(this will be about +3dBm before the 3dB pad).LO1 signal source: 0dBm into DUT at 2100MHz
(this will be about +3dBm before the 3dB pad).LO2 signal source: 0dBm into DUT at 2101MHz
(this will be about +3dBm before the 3dB pad).Disable the signal generator outputs.Connect the RF source (with pad) to the RF port.Connect the LO1 and LO2 signal sources to the EV
kit’s LO1 and LO2 inputs, respectively.Measure the loss in the 3dB pad and cable that will
be connected to the IF port. Losses are frequency
dependent, so test this at 200MHz (the IF frequency).
Use this loss as an offset in all output power/gain cal-
culations.Connect this 3dB pad to the EV kit’s IF port connec-
tor and connect a cable from the pad to the spec-
trum analyzer.Set the DC supply to +5.0V, and set a current limit
of around 175mA if possible. Disable the output
voltage and connect the supply to the EV kit
(through an ammeter, if desired). Enable the sup-
ply. Readjust the supply to get +5.0V at the EV kit.
There will be a voltage drop across the ammeter
when the mixer is drawing current.
10)Select LO2 by connecting LOSEL (TP3) to GND.
11)Enable the LO and the RF sources.
Testing the Mixer
Adjust the center and span of the spectrum analyzer to
observe the IF output tone at 201MHz. The level should
be about -10.5dBm (7.5dB conversion loss, 3dB pad
loss). The spectrum analyzer’s absolute magnitude
accuracy is typically no better than ±1dB. Use the power
meter to get an accurate output power measurement.
Disconnect the GND connection to LOSEL. It will be
pulled high by a pullup resistor on the board to select
LO1. Observe that the 200MHz signal increases while
the 201MHz decreases.
Reconfigure the test setup using a combiner or hybrid
to sum the two LO inputs to do a two-tone IP3 measure-
ment if desired. Terminate the unused LO input in 50Ω.

Detailed Description
The MAX2043 is a high-linearity up/downconverter inte-
grated with RF and LO baluns, an LO buffer, and an
SPDT LO input select switch. The EV kit circuit uses the
MAX2043 and consists mostly of supply-decoupling
capacitors, DC-blocking capacitors, a current-setting
resistor, and an IF balun. The MAX2043 EV kit circuit
allows for thorough analysis and a simple design-in.
Supply-Decoupling Capacitors
Capacitor C4 is a 22pF supply-decoupling capacitor
used to filter high-frequency noise. Capacitors C5, C7,
and C9 are larger 0.01µF used for filtering lower frequen-
cy noise on the supply.
DC-Blocking Capacitors
The MAX2043 has internal baluns at the RF and LO
inputs. These inputs have almost 0Ωresistance at DC,
and so DC-blocking capacitors C1, C6, and C8 are
used to prevent any external bias from being shunted
directly to ground.
LO Bias
Bias current for the integrated LO buffer is set with
resistor R1 (357Ω±1%). The DC current of the device
can be reduced by increasing the value of R1 but the
device would operate at reduced performance levels
(see the Modifying the EV Kitsection).
Tap Network
Capacitor C3 helps to terminate the second-order inter-
modulation products.
IF±
The MAX2043 mixer has an IF frequency range of DC
to 350MHz. Note that these differential ports are ideal
for providing enhanced IIP2 performance. Single-
ended IF applications require a 1:1 balun to transform
the 50Ωdifferential output impedance to a 50Ωsingle-
ended output. After the balun, the IF return loss is bet-
ter than 15dB. The differential IF is used as an input
port for upconverter operation. The user can use a dif-
ferential IF amplifier following the mixer, but a DC block
is required on both IF pins. In this configuration, the IF+
and IF- pins need to be returned to ground through a
high resistance (about 1kΩ). This ground return can
also be accomplished by grounding the RF tap (pin 8)
and AC-coupling the IF+ and IF- ports (pins 13 and 14).
LOSEL
The EV kit includes a 47kΩpullup resistor (R2) for easy
selection of the LO port. Providing a ground at TP3
selects LO2, and leaving TP3 open selects LO1. To
drive TP3 from an external source, follow the limits
called out in the MAX2043 device data sheet. Logic
voltages should not be applied to LOSEL without the
+5V supply voltage. Doing so can cause the on-chip
ESD diodes to conduct and could damage the device.
Layout Considerations
The MAX2043 evaluation board can be a guide for your
board layout. Pay close attention to thermal design
and close placement of components to the IC. The
MAX2043 package exposed paddle (EP) conducts
heat from the device and provides a low-impedance
electrical connection to the ground plane. The EP must
be attached to the PC board ground plane with a low
thermal and electrical impedance contact. Ideally, this
is achieved by soldering the backside of the package
directly to a top metal ground plane on the PC board.
Alternatively, the EP can be connected to an internal or
bottom-side ground plane using an array of plated vias
directly below the EP. The MAX2043 EV kit uses nine
evenly spaced 0.016in-diameter, plated through holes
to connect the EP to the lower ground planes.
Depending on the ground-plane spacing, large sur-
face-mount pads in the IF path may need to have the
ground plane relieved under them to reduce parasitic
shunt capacitance.
Modifying the EV Kit
The RF, LO, and IF ports are broadband matched, so
there is no need to modify the circuit for use anywhere
in the 1700MHz to 3000MHz RF range, 1900MHz to
3000MHz LO range, and 50MHz to 350MHz IF range.
The DC current of the device can be reduced if reduced
performance is acceptable. Reducing the current is
accomplished by increasing the value of R1. Doubling
the value of R1 reduces the DC current approximately
in half. Approximately 10% of the overall IC current is
used for basic operation of the device (R1 set at 357Ω)
and cannot be reduced.
