Abstract :
GaAs/GaAlAs heterojunction bipolar transistors (HBTs) have been fabricated. The low phase noise characteristics of HBT oscillators have been investigated and the first HBT mixer was fabricated and measured. The full experimental results are presented. A conversion factor of 4.5×1010 Hz/A has been obtained in a free-running 8-GHz oscillator. The first HBT mixer has shown a third-order intercept point comparable to a MESFET
