General Description
The MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/
MAX2327 evaluation kits (EV kits) simplify evaluation of
these high-linearity, silicon germanium (SiGe), dual-
band LNAs/mixers. They enable testing of the devices’
RF performance and require no additional support cir-
cuitry. The signal inputs and outputs use SMA connec-
tors to simplify the connection of RF test equipment.
The MAX2320/21/22/24/26/27 EV kits are assembled
with an associated IC and incorporate input and output
matching components optimized for the 869MHz to
894MHz cellular frequency band, 1930MHz to
1990MHz PCS frequency band, 210MHz digital mixer
output frequency, and 110MHz FM mixer output fre-
quency. All matching components may be changed to
work at other frequencies within the bands specified in
the MAX2320/21/22/24/26/27 data sheet.
Features
♦50ΩSMA Ports for Easy Testing
♦+2.7V to +3.6V Single-Supply Operation
♦All Critical Matching Components Included
♦Fully Assembled and Tested

_________________________________Quick Start
The MAX2320/21/22/24/26/27 EV kits are fully assem-
bled and factory tested. Follow the instructions in the
Connections and Setup section for proper device eval-
uation. Figures 1, 2, and 3 show the schematics.
Figures 4 through 9 are component placement guides
and PC board layouts.
Test Equipment Required
The adjacent table lists the required test equipment to
verify MAX2320/MAX2321/MAX2322/MAX2324/MAX2326/
MAX2327 operation. It is intended as a guide only, and
some substitutions are possible.
Connections and Setup
This section provides a step-by-step guide to operating
the EV kits and testing the devices’ functions. Do not
turn on DC power or RF signal generators until all con-
nections are made.
Testing the LNA
1) Connect a DC supply set to +2.7V (through an
ammeter if desired) to the VCC and GND terminals
on the EV kit. If available, set the current limit to
40mA.
2) Install the shunts across jumpers JU5 and JU8.
Install the shunt across JU6 to the FMMXR position
and across JU4 to the OFF position. See Tables 1–5
for positions of the shunts across JU1, JU2, and JU3
for different modes.

3) Connect one RF signal generator to the LNAINL
(LNAINH) SMA connector for cellular (PCS) band
testing. Do not turn on the generator’s output. Set
the generator for an output frequency of 881MHz
(1960MHz) for cellular (PCS) band operation. Set
the power level to -25dBm.
4) Connect the spectrum analyzer to the LNAOUTL
(LNAOUTH) SMA connector for cellular (PCS) band.
Set the center frequency to 881MHz (1960MHz) for
cellular (PCS) band, and span to 5MHz.
5) Turn on the RF signal generator. The peak that
appears on the spectrum analyzer should have a
magnitude of about -11dBm in high-gain and FM
modes. In low-gain modes, the magnitude should
be about -27dBm. Be sure to account for cable
losses (between 0.5dB and 2dB) and circuit board
losses (approximately 0.5dB) when computing gain
and noise figure.
6) (Optional) Another method for determining gain is
by using a network analyzer. This has the advan-
tage of displaying gain over a swept frequency
band, in addition to displaying input and output
return loss. Refer to the network analyzer manufac-
turer’s user manual for setup details.
Testing the Mixer
1) Connect a DC supply set to +2.7V (through an
ammeter if desired) to the VCC and GND terminals
on the EV kit. If available, set the current limit to
40mA.
2) Install the shunts across jumpers JU5 and JU8.
Install the shunt across JU6 to the FMMXR position
(except MAX2322; see Table 5) and across JU4 to
OFF. See Tables 1–4 for positions of the shunts
across JU1, JU2, and JU3 for different modes.
3) Connect an RF signal generator to the MIXINL (MIX-
INH) SMA connector for cellular (PCS) band testing.
Do not turn on the generator’s output. Set the gener-
ator for an output frequency of 881MHz (1960MHz)
for cellular (PCS). Set the power level to -25dBm.
4) See Table 5, and connect the second RF signal gen-
erator to the appropriate LO connector and set the
frequency accordingly. Set the power level to
-6dBm.
5) In FM mode, connect the spectrum analyzer con-
nector to the FMOUT SMA, set the center frequency
to 110MHz, and span to 5MHz. For all other modes,
connect the spectrum analyzer connector to the
CDMAOUT SMA and set the center frequency to
210MHz and span to 5MHz.

6) Turn on both RF signal generators. In FM mode, the
spectrum analyzer should read about -15dBm at
110MHz. In all other modes, the peak should be
about -13dBm at 210MHz. Be sure to account for
cable losses (between 0.5dB and 2dB) and circuit
board losses (approximately 0.5dB) when comput-
ing gain and noise figure.
Layout
The EV kit PC board can serve as a guide for layout
using the MAX2320/21/22/24/26/27.
Keep traces carrying RF signals as short as possible to
minimize radiation and insertion loss due to the PC
board. Keep the differential mixer output traces togeth-
er and of equal length to ensure signal amplitude bal-
ance. Solder the entire bottom side slug evenly to the
board ground plane for best RF performance. Run the
input trace to the PCS LNA on the top layer of the PC
board avoiding via-induced coupling. Minimize the par-
allel length of the cellular LNA input trace with the PCS
LNA input trace.
