Abstract
Frequency multiplier includes common-emitter input amplifying stage receiving fundamental frequency input signals at input transistor base. Output amplifying stage has output transistor with its base linked to input transistor collector, and with its collector coupled to narrow band load circuit tuned to a selected harmonic frequency. Emitter circuit of output transistor includes parallel resonant circuit tuned to input signal fundamental frequency. Non-linear negative feedback path between output transistor emitter and input transistor base includes capacitor in series with paralleled, oppositely poled diodes.
