"SERIES RESONANT CIRCUIT, RF MATCHING, INDUCTIVE LOAD, RESISTIVE INPUT. Calculates values of capacitances C1 (in pFarads) and C2 (in pFarads) required to tune or match an inductive load consisting of an inductanceXLOAD (in Ohms) and a pure resistance RLOAD (in Ohms) to a pure input resistance RIN (in Ohms) without reactance at frequency F0 (in megaHertz). ■ | | o------------|--------| |-------------| | | | C1 ) xload Rin ------- (pF) ) (Ohms) Xin=0 ------- | | C2 \ | (pF) / rload o------------|------------------------| (Ohms) ■ *** Answers to Problems *** (c) PCSCC, Inc., 1993 (a) Set F0=56, RIN=50, RLOAD=7.75 and XLOAD=148.
