Abstract
A three stage amplifier has been developed for PCS, EDGE and W-CDMA applications. Using the MESFET GaAs process of the Fujitsu foundry, we achieved a typical 30dB gain and 4 Watts output power. The input matches for a 50ohm system and the output used a pre-match circuit in order to increase its low impedance. This amplifier has a frequency range of 1.7Ghz to 2.3 Ghz.
