MAX2264/MAX2265/MAX2266 Evaluation Kits
General Description
The MAX2264/MAX2265/MAX2266 evaluation kits (EV kits) simplify evaluation of the MAX2264/MAX2265/ MAX2266 power amplifiers (PAs), which are designed for operation in IS-98-based CDMA, IS-136-based TDMA, and PDC cellular phones operating in the 900MHz range. The kits enable testing of the devices' RF performance and require no additional support circuitry. The EV kits' signal inputs and outputs use SMA connectors to facilitate the connection of RF test equipment. Each kit is assembled with either the MAX2264, MAX2265 or MAX2266 and incorporates input and output matching components optimized for the 824MHz to 849MHz RF frequency band. These EV kits are capable of operating at RF frequencies from 750MHz to 1000MHz with the appropriate matching components.
Features

MAX2264/MAX2265/MAX2266 Evaluation Kits Evaluate: MAX2264/MAX2265/MAX2266
_________________________Quick Start
The MAX2264/MAX2265/MAX2266 EV kits are fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device evaluation. 4) Connect the power sensor to the power meter. Calibrate the power sensor for 836MHz. Set the power meter offset to compensate the 20dB attenuator plus any cable loss (between 0.5dB and 2dB), and circuit board losses (approximately 0.1dB). 5) Connect a power sensor to the 20dB high-power attenuator. 6) Place the HIGH/LOW jumper (JU1) in the HIGH position and the ON/OFF jumper (JU2) in the ON position. 7) Turn on the DC supply. The supply current should read approximately 80mA to 90mA. 8) Activate the RF generator's output. Set the RF generator's output to produce a reading of +28dBm on the power meter. Verify that the voltmeter reads +3.3V. Iteratively adjust the power supply's output and the RF generator's output to produce a +3.3V reading on the voltmeter and a reading of 28dBm on the power meter. For the MAX2264, the supply current should increase to approximately 580mA. b) For the MAX2265, the supply current should increase to approximately 520mA. c) For the MAX2266, the supply current should increase to approximately 580mA. 9) For the MAX2264/MAX2266 EV kits: a) b) c) d) e) Adjust the RF generator's output to -10dBm. Turn off the RF generator's output. Place the HIGH/LOW jumper (JU1) in the LOW position. The supply current reading should drop to approximately 34mA. Activate the RF generator's output. Adjust the RF generator's output for a +16.5dBm power meter reading. Iteratively adjust the power supply's output and the RF generator's output to produce a reading of +3.3V on the voltmeter and a +16.5dBm reading on the power meter. The supply current should increase to approximately 105mA/70mA (MAX2264/MAX2266). a)
Test Equipment Required
This section lists the test equipment recommended to verify operation of the MAX2264/MAX2265/MAX2266. It is intended as a guide only, and some substitutions are possible. * An RF signal generator capable of delivering at least +10dBm of output power at the operating frequency with CDMA modulation (HP E4433G or equivalent) * An RF power sensor capable of handling at least +20dBm of output power at the operating frequency (HP 8482A, or equivalent) * 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 MAX2264/MAX2265/ MAX2266's operating frequency range (Rhodes at Schwartz FSEA20, for example) * A power supply capable of up to 1A at +2.7V to +5V * A high-impedance voltmeter for measuring the actual operating voltage * An ammeter for measuring the supply current (optional) * Two 50 SMA cables * A network analyzer (HP 8753D, for example) to measure small-signal return loss and gain (optional)
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 connections are made. 1) Connect a 20dB high-power attenuator to the OUT SMA connector on the EV kit. This will prevent overloading the power sensor and the power meter. 2) Connect a DC supply set to +3.3V (through an ammeter if desired), and connect the voltmeter to the EV kit's VCC and GND terminals. 3) Connect an RF signal generator to the IN SMA connector. Set the generator for an 836MHz output frequency at a 0dBm power level.

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 MAX2264/MAX2265/MAX2266. 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 supply 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 central VCC node, can further minimize coupling between sections of the IC.
