tuning components changing the resonant frequency of a tuned circuit can be done by varying either its inductance or capacitance because of their smaller size and higher q capacitors are generally chosen as the tuning element one way to accomplish this is by allowing the capacitance to be a bank of switched discrete capacitors far from ideal the pin diode remains the choice rf switching component when medium to high in-band rf power handling 1 to 100 watts or greater is required once a high cost component diode manufacturers now offer high performance parts in low cost smd packages some jfets are available that exhibit usable rf switch characteristics but rf power handling can only approach the 1 watt level varactor diodes remain the choice tuning element for rf power handling to 20mw insertion loss il and bandwidth/selectivity an unfortunate rule of nature dictates that a filter s insertion loss and bandwidth are inversely related the narrower the bandwidth of a filter of a given tech
