DCS-band 4W HBT Amplifier Module
Product Description
The AP503 is a high dynamic range power amplifier in a Ro HS-pliant flange-mount package. The multi-stage amplifier module has 31.5 d B gain. The module has been internally optimized for linearity to provide +25 d Bm (-64 d Bc ACPR) linear power for 7-carrier CDMA2000 applications. The AP503 uses a high reliability In Ga P/Ga As HBT process technology and does not require any external matching ponents. 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...
