Switch for transmit/receive mode selection and antenna polarization diversity

摘要

A transceiver circuit includes a transmitter to send communication signals and a receiver to receive communication signals sent by other transmitters. The transceiver circuit also includes a switch to connect the transmitter and the receiver to at least one antenna. The switch controls at least two directions of polarization of the at least one antenna.

1. A transceiver circuit, comprising:
a transmitter configured to send communication signals; a receiver configured to receive communication signals sent by other transmitters; and a first switch configured to couple the transmitter and the receiver to an antenna, the first switch to control at least two directions of polarization of the antenna, the first switch comprising four single-pole, single-throw switches coupled in shunt to one another, the four single-pole, single-throw switches configured to operate as a double-pole, double-throw switch.
