Abstract :
The d.c.--r.f. conversion efficiencies, microwave output power and r.f. impedance have been calculated for InP and GaAs bulk-negative-resistance oscillators (l.s.a. mode) using theoretical velocity/field characteristics at 300 K and 500 K. The results predict higher efficiency and higher power--impedance products for InP at 500 K.
