General Description
____________________________Features
ꢀ Easy Evaluation of MAX2267/MAX2268/MAX2269
ꢀ +2.7V to +4.5V Single-Supply Operation
The MAX2267/MAX2268/MAX2269 evaluation kits (EV
kits) simplify evaluation of the MAX2267/MAX2268/
MAX2269 power amplifiers (PAs), which are optimized
for IS-98-based CDMA and PDC cellular phones oper-
ating in the Japanese cellular frequency band. The kits
enable testing of the devices’ RF performance and
require no additional support circuitry. The EV kits’ sig-
nal inputs and outputs use SMA connectors to facilitate
the connection of RF test equipment.

Each kit is assembled with the MAX2267, MAX2268, or
MAX2269 and incorporates input and output matching
components optimized for the 887MHz to 925MHz RF
frequency band. These EV kits are capable of operat-
ing at RF frequencies from 750MHz to 1000MHz, with
the appropriate matching components.

attenuator.
These EV kits are fully assembled and factory-tested.
6) Place the HIGH/LOW jumper (JU1) in the HIGH
position and the ON/OFF jumper (JU2) in the ON
position.
Follow the instructions in the Connections and Setup
section for proper device evaluation.
Test Equipment Required
This section lists the test equipment recommended to
verify operation of the EV kits. It is intended as a guide only,
and some substitutions are possible.
7) Turn on the DC supply. The supply current should
read approximately 90mA to 100mA.
8) Activate the RF generator’s output. Set the RF gener-
ator’s output to produce a reading of +27dBm on the
power meter. Verify that the voltmeter reads +ꢁ.5V.
Iteratively adjust the power supply’s output and the
RF generator’s output to produce a +ꢁ.5V reading on
the voltmeter and a reading of 27dBm on the power
meter:
• An RF signal generator capable of delivering at least
+10dBm of output power at the operating frequency
with CDMA modulation (HP E44ꢁꢁG, or equivalent)
• An RF power sensor capable of handling at least
+20dBm of output power at the operating frequency
(HP 8482A, or equivalent)
a) For the MAX2267, the supply current should
increase to approximately 490mA.
• A 20dB high-power attenuator
• An RF power meter capable of measuring up to
+20dBm of output power at the operating frequency
(HP EPM-441A, or equivalent)
• An RF spectrum analyzer capable of measuring ACPR
and covering the MAX2267/MAX2268/MAX2269’s
operating frequency range (Rhodes at Schwartz
FSEA20, for example)
b) For the MAX2268, the supply current should
increase to approximately 420mA.
c) For the MAX2269, the supply current should
increase to approximately 480mA.
9) For the MAX2267/MAX2269 EV kits:
a) Adjust the RF generator’s output to -10dBm.
Turn off the RF generator’s output.
• A power supply capable of up to 1A at +2.7V to +5V
• A high-impedance voltmeter for measuring the actual
operating voltage
b)Place the HIGH/LOW jumper (JU1) in the LOW
position.
• An ammeter for measuring the supply current (optional)
• Two 50Ω SMA cables
c) The supply current reading should drop to
approximately ꢁ4mA.
• A network analyzer (HP 875ꢁD, for example) to mea-
sure small-signal return loss and gain (optional)
d)Activate the RF generator’s output.
e) Adjust the RF generator’s output for a +17dBm
power meter reading. Iteratively adjust the power
supply’s output and the RF generator’s output to
produce a reading of +ꢁ.5V on the voltmeter and
a +17dBm reading on the power meter. The sup-
ply current should increase to approximately
120mA/90mA (MAX2267/MAX2269).
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 the DC power or RF signal generator until all con-
nections are made:
1) Connect a 20dB high-power attenuator to the OUT
SMA connector on the EV kit. This will prevent over-
loading the power sensor and the power meter.
_______________________ Layout Issues
A good PC board is an essential part of an RF circuit
design. The EV kit PC board can serve as a guide for
laying out a board using the MAX2267/MAX2268/
MAX2269. Keep traces carrying RF signals as short as
possible to minimize radiation and insertion loss due to
the PC board. Each VCC node on the PC board should
have its own decoupling capacitor. This minimizes sup-
ply coupling from one section of the IC to another. Using
a star topology for the supply layout, in which each VCC
node on the circuit has a separate connection to a cen-
tral VCC node, can further minimize coupling between
sections of the IC.
2) Connect a DC supply set to +ꢁ.5V (through an
ammeter if desired), and connect the voltmeter to the
EV kit’s VCC and GND terminals.
ꢁ) Connect an RF signal generator to the IN SMA con-
nector. Set the generator for a 906MHz output fre-
quency at a 0dBm power level.
4) Connect the power sensor to the power meter.
Calibrate the power sensor for 906MHz. Set the
power meter offset to compensate the 20dB attenua-
tor plus any cable loss (between 0.5dB and 2dB) and
circuit board losses (approximately 0.1dB).
