Product Description
The AP512 is a high dynamic range power amplifier in a
RoHS-compliant flange-mount package. The multi-stage
amplifier module has 28.5 dB gain, while being able to
achieve high performance for UMTS-band applications with
+39 dBm of compressed 1dB power. The module has been
internally optimized for linearity to provide -55 dBc ALCR
at 28 dBm power for W-CDMA applications.
The AP512 uses a high reliability InGaP/GaAs HBT process
technology and does not require any external matching
components. The module operates off of 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 and achieves over
100 years MTTF. All devices are 100% RF and DC tested.
The AP512 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 or repeaters using the UMTS frequency band.
