AP503

www.DataSheet4U.com AP503 Product Features 1805 – 1880 MHz 32.2 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. Functional Dia...
