Abstract
Self-aligned GaAs junction field effect transistor (JFET) narrowband amplifiers operating at 2.4 GHz have been designed and fabricated both with discrete JFETs as a hybrid amplifier and as radiofrequency integrated circuits (RFICs). Enhancement-mode JFETs were used in order to be compatible with complementary digital logic. Hybrid amplifiers achieved 8-10 dB of gain at 2.4 GHz and 1 mW DC bias level. The RFIC achieved 10 dB of gain at 2.4 GHz and 2 mW DC bias level
