THE SMART TRICK OF LOW-NOISE AMPLIFIER THAT NOBODY IS DISCUSSING

This kind of circuit is known as a resonant switch and is also inherently slim band. Depending upon the loaded Q of the parallel resonant circuit, the handy bandwidth is typically restricted to ten% in the centre frequency or a lot less. A capacitor (Cblk ) is additional in collection for the inductor to circumvent shorting of the PIN diode at DC.
