Specifications of MAX2321EVKIT

• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

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.
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.
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.
1) Connect a DC supply set to +2.7V (through an

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.
EQUIPMENT
Capable of delivering at least 0dBm of
output power up to 2.5GHz (HP 8648C
or equivalent)
Capable of covering the operating
frequency range of the devices as well
as a few harmonics (HP 8561E, for
example)
Capable of up to 100mA at +2.7V to
+3.6V
For measuring the supply current
(optional)
To measure small-signal return
loss and gain (optional, HP 8753D,
for example)
