Quick Start
MAX2291 EV kits are fully assembled and factory tested. Follow the instructions in the Connections and Setup section for proper device evaluation. 1) Connect a DC supply set to +3.5V (through an ammeter if desired) to the VCC and GND terminals on the EV kit. Do not turn on the supply. 2) Connect one RF signal generator to the IN1 SMA connector; do not turn on the generator's output. Set the generator for output frequency and power level according to Table 1. 3) Connect a 20dB pad to the OUT SMA connector on the EV kit. This is to prevent overloading of the power sensor and the power meter. 4) Connect a power sensor to the 20dB pad. 5) Connect the power sensor to a power meter. Set the power meter offset to 20dB and frequency according to Table 1. For more accuracy, measure the actual offset. 6) Connect jumpers JU1 and JU2 to make SHDN = VCC, MODE = GND. This sets the MAX2291 to highpower mode. The MAX2291 EV kit is shipped in this setting. 7) Turn on the DC supply. The supply current should read approximately 170mA. 8) Activate the RF generator's output. The power meter should read approximately +29dBm (N-CDMA). The supply current should increase to approximately 630mA (N-CDMA). See Table 1 for approximate readings in other modes. 9) Another method for determining gain is by using a network analyzer (optional). This has the advantage of displaying gain versus a swept-frequency band, in addition to displaying input return loss. Refer to the network analyzer manufacturer's user manual for setup details.
Test Equipment Required
This section lists the test equipment recommended to verify operation of the MAX2291. It is intended as a guide only, and some substitutions are possible: * One RF signal generator capable of delivering at least +5dBm of output power at the operating frequency (HPE4433B or equivalent) * One RF power sensor capable of handling at least +20dBm of output power at the operating frequency (HP 8482A or equivalent) * One RF power meter capable of measuring up to +20dBm of output power at the operating frequency (HP 437B or equivalent) * An RF spectrum analyzer that covers the MAX2291 operating frequency range, as well as a few harmonics (FSEB20, for example) * A power supply capable of up to 1A at +2.7V to +4.2V * An optional ammeter for measuring the supply current * Two SMA cables * One SMA 20dB pad * 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 kit and testing the device's function. Do not turn on the DC power or RF signal generators until all connections are made.
