Product Description
The AP622 power amplifier module is a two-stage power
amplifier module that operates over the frequency range of
2110 – 2170 MHz and is housed in a small, RoHS-
compliant, flange-mount package. 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.
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.
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.
