Abstract:
1. A wide range tunable capacitor bank, comprising: a variable capacitor, the capacitance value of which is adjustable within a predetermined capacitance range defined by a minimum capacitance value and a maximum capacitance value; and one or more switched capacitors electrically connected to the variable capacitor, wherein each of the one or more switched capacitors has a first capacitance value corresponding to an un-actuated state and a second capacitance value corresponding to an actuated state, and further wherein the second capacitance value is greater than the first capacitance value and less than or equal to the maximum capacitance value of the variable capacitor, and further wherein the variable capacitor is configured to allow the capacitance value thereof to be adjusted within the predetermined capacitance range and the one or more switched capacitors are configured to be selectively actuated to permit continuous tuning of the capacitor bank over a second capacitance range that is greater than the predetermined capacitance range.
