Abstract
A hybrid diode silicon on insulator front end module and related method are provided. The front end module includes a transmit branch that includes a transmit circuit and a receive branch that includes a receive circuit. The receive circuit includes a low noise amplifier, a pin diode including an anode and a cathode; and a switch. The anode of the pin diode is operatively connected to an antenna switch port and an input voltage source. The cathode of the pin diode is operatively connected to a cathode of the switch. Turning on the switch facilitates a drainage of residual electrical current at the pin diode.
