Recommended Test Equipment
Power supply capable of providing 100mA at +2.9V
to+3.3V
Two RF signal generators capable of delivering
-70dBm to -10dBm of output power from 450MHz to
1200MHz (HP 8658C or equivalent)
Network analyzer covering the MAX2335 operating
frequency range (HP 8753 or equivalent)
Spectrum analyzer covering the MAX2335 operating
frequency range (HP 8561E or equivalent)
Ammeter (optional) for measuring supply current
Noise figure meter (optional) for measuring the noise
figure of the LNA and downconverters (HP 8970B or
equivalent)
Quick Start
The MAX2335 EV kit is fully assembled and factory tested.
Follow the instructions in the
Connections and Setup
sec-
tion for proper device evaluation.
Connections and Setup
This section provides a step-by-step guide to setting
up the MAX2335 EV kit and testing the LNA and down-
converters.
Do not turn on the DC power or RF sig-
nal generators until all connections are made.
Low-Noise Amplifier, High-Gain
High-Linearity Mode
1) Set Mode 0 (JU1), Mode 1 (JU3), and Mode 2 (JU4) on
the EV kit to VCC (high). This enables the LNA to oper-
ate in the high-gain and high-linearity mode.
2) Connect a DC supply preset to +3V (through an
ammeter, if desired) to the EV kit’s VCC and GND
terminals. Do not turn on the supply.
3) Perform a full two-port calibration on a network ana-
lyzer at a -30dBm power level over a 400MHz to
500MHz frequency range.
4) Connect port 1 and port 2 of the network analyzer
to LNAIN and LNAOUT, respectively, to measure
the gain at 465MHz.
5) The network-analyzer display should indicate a typ-
ical gain of 16dB at 465MHz after accounting for
board losses. The input and output board losses
are 0.3dB at the 465MHz band. These losses are to
be added to the measurements to obtain the perfor-
mance of the LNA.
Downconverter, High-Gain High-Linearity Mode
1) Turn off the DC supply.
2) Remove the network analyzer from the LNA input
and output connections. The DC supply connec-
tions for testing the downconverter mixer are the
same as the LNA section.
3) Set the LO/2 jumper (JU5) to VCC to enable the LO
divider circuit.
4) The mode setting for testing the downconverter
mixer is the same as the LNA section.
5) Connect an RF signal generator (with output dis-
abled) to the LOIN connector. Set the frequency to
1150MHz and the output power to -7dBm.
6) Connect another RF signal generator (with output
disabled) to the MIXIN SMA connector. Set the fre-
quency to 465MHz and the output power to -40dBm.
7) Connect the spectrum analyzer to the IFOUT SMA
connector. Set the spectrum-analyzer center fre-
quency to 110MHz.
8) Turn on the DC supply. Enable the LO signal gener-
ator and RF input signal generator outputs.
9) Measure the peak of the 110MHz IF signal on the
spectrum analyzer. Compensate the IF signal con-
version gain of the balun and the board losses. The
balun loss is approximately 0.3dB and the input
and output board losses are 0.1dB each.
10) The conversation gain is approximately 13dB after
corrections from step 9 are applied.
