摘要
A wideband, microwave regenerative divider with varactor tuning in which a double-balanced mixer is incorporated in a feedback loop with a varactor-tuned filter and an RF amplifier in the forward loop, with the RF amplifier output fed directly back to the mixer. A series resonant circuit formed by two serially connected back-to-back varactors interconnected by an inductor is tuned by application of a DC tuning voltage to a center tap of the inductor. In the preferred embodiment two regenerative dividers are connected in series in a YIG oscillator system which includes a programmable tuning circuit connected between the VCO tuning signal input for the YIG oscillator and the tuning voltage inputs of the respective regenerative dividers.
