General Description
The MAX2205MAX2208 evaluation kits (EV kits) simplify
the evaluation of the MAX2205MAX2208 RF power
detectors. They enable testing of all functions, with no
additional support circuitry. The RF input utilizes a
50
SMA connector for convenient connection to test
equipment.

Quick Start
The MAX2205MAX2208 EV kits are fully assembled and
factory tested. Follow the instructions in the Connections
and Setup section for proper device setup.
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:
1) Set the SHDN jumper (JU1) on the EV kit to ON. This
enables the device.
2) Connect a DC supply set to +2.85V (through a DMM,
if desired) to the V
CC
and GND terminals on the EV
kit. If available, set the current limit to 10mA. Do not
turn on the supply.
3) Connect the output (J3) to a DMM to measure output
voltage.
4) Set the signal generator output to +15dBm,
f = 800MHz. For the MAX2206, use a CW input from
the signal generator to the RF input. For the MAX2207,
use a TDMA input. For the MAX2205/MAX2208, use a
CDMA input. Using the power meter, determine the
actual power output of the signal generator. Use this
value to determine proper operation of the part.
5) Connect the signal generator to the SMA connector.
Do not turn on the signal generator.
6) Turn on the DC supply; the supply current should
read approximately 3.5mA (MAX2206) or 2mA
(MAX2205/MAX2207/MAX2208), depending on the
part being tested.
7) Activate the signal generator. The output voltage
should read approximately +1.8V for the MAX2206/
MAX2207/MAX2208, or +0.25V for the MAX2205.
