MAX2247 Evaluation Kit
General Description
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_OUT =
+24dBm. For lower power applications, see Table 2 for
appropriate matching components.

Quick Start
The MAX2247 EV kit is fully assembled and factory test-
ed. Follow the instructions in the Connections and
Setup section for proper device evaluation.
Test Equipment Required
Table 1 lists the required test equipment to verify
MAX2247 operation. It is intended as a guide only, and
some substitutions are possible.
Connections and Setup
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-
nector on the EV kit. This prevents overloading of
the power sensor and power meter.
2) Connect a DC supply set to +3.3V (through an amme-
ter, if desired) and connect a voltmeter to the EV kit’s
VCC and GND terminals. Do not turn on the supply.
3) Connect an RF signal generator to the IN SMA con-
nector. Calibrate the generator to produce an
802.11b compatible -10dBm signal, at 2.45GHz
output frequency. Do not turn on the output.
4) Connect the power sensor to the power meter.
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).
