Usefui in VF0 output circuits where oscillator operates at half output frequency of doubler. Circuit helps reduce osdllator instability during load changes while having about same efficieney as straight amplifier. Uses two sections of RCA CA3028A differential amplifier as doubler (U1C is not used).Values of tuned circuit depend on frequency, which can be up to 120 MHz.-D.
