ABSTRACT:
A microwave varactor network wherein parametric oscillation modes are suppressed by coupling the varactor, with very low intervening impedence, to a bias regulator circuit (preferably an emitter follower circuit) through which the varactor bias voltage is supplied. The emitter follower is biased to always be carrying current, which improves its response time in compensating any transient bias voltage variations which appear across the varactor.
