GETTING MY LOW-NOISE AMPLIFIER TO WORK

Such a circuit is known as a resonant switch which is inherently narrow band. Depending on the loaded Q of your parallel resonant circuit, the valuable bandwidth is usually limited to 10% of your centre frequency or much less. A capacitor (Cblk ) is added in sequence to the inductor to avoid shorting in the PIN diode at DC. The worth of Lres is oft
