摘要： A high efficiency radio frequency (RF) impedance matching network containing an "L-type" inductor-capacitor (LC) circuit where the capacitor is a variable capacitor coupled from an input port to ground and the inductor is a variable inductance inductor coupled from the input port to an output port. A blocking capacitor is provided between the inductor and the output port and a ceramic capacitor is coupled in parallel across the variable capacitor. The impedance match is tuned by physically adjusting tuning elements of both the inductor and capacitor. The variable inductor contains an improved inductor tuning element that optimizes current flow in the tuning elements and inductor. To further improve the efficiency of the matching network, the assembly uses an improved enclosure interior finish and various circuit optimization techniques that reduce contributions to match loop resistance.
