Abstract
A gallium arsenide (GaAs) radio frequency (RF) circuit is disclosed. The GaAs RF circuit includes a power amplifier and a low noise amplifier; a first transmit/receive (TR) switch, coupled to the power amplifier and the low noise amplifier, wherein the first TR switch is fabricated by a pHEMT (Pseudomorphic High Electron Mobility Transistor) process; and a first active phase shifter, coupled to the power amplifier or the low noise amplifier, wherein the first active phase shifter is fabricated by an HBT (Heterojunction Bipolar Transistor) process; wherein the GaAs RF circuit is formed within a GaAs die.
