Abstract

PURPOSE:To simplify the constitution of oscillator to obtain two different frequencies without lowering the performance, by giving the amplifying and frequency conversion functions for oscillation with the amplifier constituting the oscillation loop. CONSTITUTION:The oscillation loop consisting of the amplifier 21, band pass filter 22, branch circuit 23, synthesis circuit 24, and amplifier 21 is oscillated in frequency fT. At the synthesis circuit 24 inserted to the prestage of the amplifier 21 of this oscillation loop, the output signals fs and fT of the shifted frequency oscillation circuit 26 are synthesized and fed to the input of the amplifier 21. The amplifier 21 is used at nonlinear characteristic region and has the function of frequency conversion.
