2 dB Gain • +25 dBm CDMA2k 7fa Power (-64 dBc ACPR) The Communications Edge TM Product Information DCS-band 4W HBT Amplifier Module Product Description The AP503 is a high dynamic range power amplifier in a RoHS-compliant flange-mount package.
The multi-stage amplifier module has 31.
5 dB gain.
The module has been internally optimized for linearity to provide +25 dBm (-64 dBc ACPR) linear power for 7-carrier CDMA2000 applications.
The AP503 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.
While the module has been tuned for optimal performance for Class AB applications, the quiescent current can also be adjusted for Class B applications through an external resistor.
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 AP503 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 using the DCS1800 frequency band.
