Evaluates: MAX2204 19-0779 Rev 0 3/07 MAX2204 Evaluation Kit General Description Features The MAX2204 evaluation kit (EV kit) simplifies evalua- +2.7V to +3.3V Single-Supply Operation tion of the MAX2204 RF power detector. The EV kit 50 SMA RF Input Port Connector enables testing of all functions with no additional sup- port circuitry. The RF power-detector input uses a 50 Fully Assembled and Tested SMA connector on the evaluation board for convenient connection to test equipment. Ordering Information PART TEMP RANGE IC PACKAGE MAX2204EVKIT+ -40C to +85C 5 SC70 +Denotes a lead-free and RoHS-compliant EV kit.

Layout Issues 2) Connect a DC supply set to +2.85V (through a DMM, if desired) to the VCC and GND terminals on The MAX2204 is not particularly sensitive to the layout, the EV kit. If available, set the current limit to 10mA. since it only needs 5dBm for maximum output voltage. Do not turn on the supply. However, there are two areas that need attention: the GND pin and the supply bypassing. Connect the GND 3) Connect the output (J3) to a DMM to measure output pin to PCB ground with a GND via as close as possible, voltage. and place the supply bypassing capacitor close to the 4) Set the signal generator output to +5dBm, part. f = 836MHz.
