Abstract
A variable capacitance network is disclosed, comprising a plurality of capacitance arms connected in parallel with each other between first and second terminals of the network. Each capacitance arm has a varactor and a series capacitor in series with the varactor A control input applies a common control signal to the junctions between the varactors and their associated series capacitors, to allow for simultaneous control of each varactor.
