The MAX2247 evaluation kit (EV kit) simplifies evalua-

tion of the MAX2247 power amplifier (PA). The kit

enables testing of the device’s RF performance and

requires no additional support circuitry. The EV kit input

and output use SMA connectors to facilitate the con-

nection to RF test equipment.

Each kit is assembled with the MAX2247 and incorpo-

rates all matching components optimized for the

2.4GHz to 2.5GHz RF frequency band, and P

+24dBm. For lower power applications, see Table 2 for

appropriate matching components.

MAX2247 Evaluation Kit

♦ Easy Evaluation of MAX2247

♦ +2.7V to +3.6V Single-Supply Operation

♦ Output Matched for 2.4GHz to 2.5GHz Operation

♦ Fully Assembled and Tested

The MAX2247 EV kit is fully assembled and factory test-

ed. Follow the instructions in the Connections and

Setup section for proper device evaluation.

Table 1 lists the required test equipment to verify

MAX2247 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 kit and testing the device’s functions. Do not turn

on DC power or RF signal generators until all connec-

tions are made.

Testing the Supply Current

1) Connect a 20dB attenuator to the OUT SMA con-

2) Connect a DC supply set to +3.3V (through an amme-

3) Connect an RF signal generator to the IN SMA con-

4) Connect the power sensor to the power meter.

VCC and GND terminals. Do not turn on the supply.

nector. Calibrate the generator to produce an

802.11b compatible -10dBm signal, at 2.45GHz

output frequency. Do not turn on the output.

Calibrate the power sensor for 2.45GHz. Set the

power meter offset to compensate the 20dB attenua-

tor, the coupler, and any cable loss (from 0.5dB to

2dB), and circuit board losses (approximately 0.3dB).
