Abstract :
It is demonstrated that planar GaAs and InP field-effect-controlled transferred electron device oscillators are attractive MMIC (monolithic microwave integrated circuit) compatible candidates for local oscillator applications at Ka-band and possibly at higher frequencies, as they are not transit-time-limited as conventional transferred electron oscillators and field-effect transistors are. 55-mW 34-GHz InP, 56-mW 29-GHz GaAs, and 39-mW 37-GHz GaAs lateral MMIC-compatible transferred electron oscillators with MESFET injection contacts have been fabricated exhibiting 2.9, 5.3, and 4.9% efficiencies, respectively. Continuous-wave power levels are somewhat lower (30 mW).<>
