Popis:	A two stage high power amplifier consisting of a 325W High Voltage HBT (HVHBT) Doherty final and a 20W LDMOS Doherty driver has been developed for use in wireless basestation applications. The lineup achieved greater than 54% PAE at 75W (48.77dBm) average output power with 30dB gain while achieving -55dBc linearized ACPR at 5MHz offset using a 2C11 WCDMA input signal with 6.5dB PAR signal. The DPD friendly characteristics of the HVHBT Doherty final enable use of a non-linear Doherty driver while maintaining the same ease of correction for the overall lineup.
