Abstract :
The system power amplifier´s linearity sets the maximum bit rate and the efficiency determines the maximum output power possible given a fixed heat dissipation or DC supply. This paper demonstrates that using a GaAs PHEMT 0.15μm gate process, industry leading performance can be attained. Shown is a 15GHz linear power amplifier capable of - 52dBc IM3 at 21dBm output power (+47dBm OIP3). Also demonstrated is a 30GHz saturated power amplifier capable of making 38dBm (6W) output power at 38% peak power added efficiency. Both are fully matched to 50 Ω and have over 20dB of gain. Both are housed in a low cost laminate surface mount package.
