ABSTRACT:
A broadband PIN diode transmit/receive switch. The switch is used for electrically coupling a single antenna alternately to a transmitter and to a receiver. A first PIN diode for switching is connected between the antenna and an output port of a second order network, an input port of the second order network being connected to an output of the transmitter. A tuned tank circuit has an input port connected to the antenna and has an output port connected to an input of the receiver. A second PIN diode for switching is connected from the output port of the tuned tank circuit to an RF ground. A DC source controls the PIN diodes. When both diodes are forward biased the transmitter is connected to the antenna and is provided a good impedance match over a substantial bandwidth, otherwise the receiver is connected to the antenna.
