Quick Start
The MAX2031 EV kit is factory configured as an upcon-
verter and tuned for an 810MHz RF frequency. This is
accomplished by including components L1 and C4 on the
PC board (see the
Modifying the EV Kit
section for details.
The MAX2031 EV kit is fully assembled and factory tested.
Follow the instructions in the
Connections and Setup
sec-
tion for proper device evaluation.
Test Equipment Required
This section lists the recommended test equipment to
verify the operation of the MAX2031. It is intended as a
guide only, and substitutions may be possible.
One DC supply capable of delivering +5.0V and
150mA
Three RF signal generators capable of delivering
10dBm of output power in the 100MHz to 1GHz fre-
quency range (i.e., HP 8648)
One RF spectrum analyzer with a 100kHz to 3GHz
minimum frequency range (HP 8561E)
One RF power meter (HP 437B)
One 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 cellular
band high-side-injected LO for upconverter operation
to an 810MHz RF signal. Choose the test frequency
based on the particular system
’
s frequency plan, and
adjust the following procedure accordingly. See Figure
1 for the mixer test setup diagram.
1) Calibrate the power meter. For safety margin, use a
power sensor rated to at least +20dBm, or use
padding to protect the power head as necessary.
2) 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.
3) Use the power meter to set the signal generators
according to the following:
IF signal source: 0dBm into DUT at 160MHz
(approximately 3dBm before the 3dB pad)
LO1 signal source: 0dBm into DUT at 970MHz
(approximately 3dBm before the 3dB pad)
LO2 signal source: 0dBm into DUT at 969MHz
(approximately 3dBm before the 3dB pad)
4) Disable the signal generator outputs.
5) Connect the IF source (with pad) to the IF port.
6) Connect the LO1 and LO2 signal sources to the EV
kit LO inputs.
7) Measure loss in the 3dB pad and cable that will be
connected to the RF port. Losses are frequency-
dependent, so test this at 810MHz (the RF frequen-
cy). Use this loss as an offset in all output
power/gain calculations.
8) Connect this 3dB pad to the EV kit
’
s RF port con-
nector and connect a cable from the pad to the
spectrum analyzer.
9) Set DC supply to +5.0V, and set a current limit of
around 150mA if possible. Disable the output voltage
and connect the supply to the EV kit (through an
ammeter, if desired). Enable the supply. Readjust the
supply to get +5.0V at the EV kit. There will be a volt-
age drop across the ammeter when the mixer is
drawing current.
10) Select LO1 by connecting LOSEL (TP3) to GND.
11) Enable the LO and the RF sources.
The procedure for downconverter operation from RF to
the IF band is similar to the steps listed above. For
downconverter operation, connect the RF signal source
(with pad) to the RF port and connect a 3dB pad and
cable to the IF port from the spectrum analyzer.
