Product Features

@ 27 dBm IS-95A linear power

@ 26.5 dBm wCDMA linear power

Applications

PA mobile infrastructure

Product Description

The AP501 is a high dynamic range power amplifier in a

RoHS-compliant flange-mount package.

The multi-stage

amplifier module has 32.5 dB gain, while being able to

achieve high performance for PCS-band applications with

+36 dBm of compressed 1dB power. The module has been

internally optimized for driver applications provide -62 dBc

ACPR at 27 dBm for IS-95A applications or -55 dBc ACLR

at 26.5 for wCDMA applications. The module can be biased

down for current when higher efficiency is required.

The AP501 uses a high reliability InGaP/GaAs HBT process

technology and does not require any external matching

components. The module operates off a +12V supply and

does not requiring any negative biasing voltages; 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.

The AP501 is targeted for use as a driver or final 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.
