CONSIDERATIONS TO KNOW ABOUT LOW-NOISE AMPLIFIER

This kind of circuit is referred to as a resonant switch and is inherently slender band. Dependant upon the loaded Q on the parallel resonant circuit, the useful bandwidth is typically limited to 10% on the centre frequency or fewer. A capacitor (Cblk ) is added in sequence into the inductor to stop shorting of the PIN diode at DC. The value of Lre
