FAST VARIABLE RF NETWORK INDUCTOR

Abstract

A variable RF inductor network having a plurality of coaxial cables with their respective outer conductors in electrical contact with each other, thereby forming a common outer conductor. This common outer conductor is connected to an RF ground and an RF source. An RF choke is formed between the RF ground and RF source by winding the coaxial cables around a first of a series of inductor cores. The coaxial cables are then wound serially about the remaining succession of inductor cores to form serial, separate inductors. At each separate inductor core, one of the cables is terminated and the inner conductor of the terminated cable is connected to a PIN diode switch for switching the particular inductor out of the network by shorting the common outer conductor across the core. The inner conductors are connected to a biasing means for individually controlling each PIN diode switch to selectively switch particular inductors in and out of the network.
