HOW PIN DIODE SWITCH CAN SAVE YOU TIME, STRESS, AND MONEY.

This type of circuit is referred to as a resonant switch and it is inherently narrow band. Depending upon the loaded Q with the parallel resonant circuit, the helpful bandwidth is often limited to 10% of the centre frequency or considerably less. A capacitor (Cblk ) is added in series to the inductor to stop shorting in the PIN diode at DC. The val
