NOT KNOWN DETAILS ABOUT PIN DIODE SWITCH

This type of circuit is known as a resonant switch which is inherently slender band. Depending on the loaded Q in the parallel resonant circuit, the useful bandwidth is typically limited to 10% of the centre frequency or less. A capacitor (Cblk ) is added in sequence into the inductor to stop shorting with the PIN diode at DC. The worth of Lres cou
