Abstract
A system with a transmit-receive switch. In some embodiments, the system includes a composite switch. The composite switch may have a common port, a transmit port, and a receive port. The composite switch may include a first simple switch coupled between the common port and the receive port; and a second simple switch coupled between the common port and the transmit port. The first simple switch may be a four-quadrant switch, or the second simple switch may include a field effect transistor, and an isolated gate driver connected to the gate of the field effect transistor.
Claims22
A system, comprising:
- a composite switch,
- the composite switch having a common port, a transmit port, and a receive port, and comprising:
- a first simple switch coupled between the common port and the receive port;
- and
- a second simple switch coupled between the common port and the transmit port,
- the composite switch being configured:
