Abstract :
Intelligent RF Power Module accommodates advanced PHEMT (Pseudomorphic HEMT) die and a Automatic Bias Control (ABC) system Si die on a small ceramic substrate. This 3.5 V RF Power Module has been designed for use in PCS CDMA applications. At PCS frequency of 1880 MHz, the module attained 35% PAE at Po=28 dBm.
