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.
