The multi-stage amplifier module has a 28 dB gain, P1dB of 35dBm, and ACLR of –55dBc at +23 dBm output power for WCDMA applications. 1 2 3 4 5 6 Top View The AP622 uses a +28V high reliability InGaP/GaAs HBT process technology and does not require any external matching components. The amplifier module operates off a +28V supply; an internal active bias allows the amplifier to maintain high linearity over temperature. It has the added feature of a +5V power down control pin. A low-cost metal housing allows the device to have a low thermal resistance to ensure long lifetimes. All devices are 100% RF and DC tested. Pin No. 1 2/4 3/5 6 Case Function RF Output Vcc Vpd RF Input Ground The AP622 is targeted for use as a driver stage amplifier in wireless infrastructure where high linearity and high power is required. This combination makes the device an excellent candidate for next generation multi-carrier 3G base stations.

The sequencing is not required in the final system application. 5V 28V GND 28V Turn-on Sequence: 1. 2. 3. 4. Attach input and output loads onto the evaluation board. Turn on power supply Vcc = +28V. Turn on power supply Vpd = +5V. Turn on RF power. Turn-off Sequence: 1. 2. 3. Notes: 1. Turn off RF power. Turn off power supply Vpd = +5V. Turn off power supply Vcc = +28V. Vpd is used as a reference for the internal active bias circuitry. It can be used to turn on/off the amplifier.

Please note that for reliable operation, the evaluation board will have to be mounted to a much larger heat sink during operation and in laboratory environments to dissipate the power consumed by the device. The use of a convection fan is also recommended in laboratory environments. Details of the mounting holes used in the WJ heatsink are given on the last page of this datasheet. 2. The area around the module underneath the PCB should not contain any soldermask in order to maintain good RF grounding. 3. For proper and safe operation in the laboratory, the power-on sequencing should be followed: a. Connect RF In and Out b. Connect the voltages and ground pins as shown in the circuit. c. Apply the RF signal d.
