MAX2205-MAX2208 Evaluation Kits
General Description
The MAX2205-MAX2208 evaluation kits (EV kits) simplify the evaluation of the MAX2205-MAX2208 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. o 50 SMA Connector on RF Input o Fully Assembled and Tested
Features
o +2.7V to +5V Single-Supply Operation

MAX2205-MAX2208 Evaluation Kits Evaluate: MAX2205-MAX2208
Quick Start
The MAX2205-MAX2208 EV kits are fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device setup.
Test Equipment Required
EQUIPMENT Signal Generator with Digital Modulation Capabilities Power Meter Power Supply Digital Multimeters (DMMs) DESCRIPTION Capable of delivering continuous wave (CW), CDMA, and TDMA signals with +15dBm output power To accurately measure the power into the RF input Capable of up to 10mA at +2.7V to +6V To measure output voltage and supply and output current
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 connections 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 VCC 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.
