Abstract
An apparatus comprises an input port, an output port, and a resonant receive switch circuit. The resonant receive switch circuit may be coupled between the input port and the output port. The resonant receive switch circuit may comprise a switch and an input matching circuit. When the switch is in a non-conducting state, a signal at the input port is passed to the output port. When the switch is in a conducting state, the signal at the input port is prevented from reaching the output port.

An apparatus comprising:
- an input port;
- an output port;
- and
- a resonant receive switch circuit coupled between the input port and the output port, said resonant receive switch circuit comprising a switch and an input matching circuit, wherein (i) said switch is ac coupled between said input port and said output port, (ii) when said switch is in a non-conducting state, a signal at the input port is passed to the output port, and (iii) when said switch is in a conducting state, the signal at the input port is reflected.
A transceiver front end circuit comprising:
- an antenna port;
- an output port;
- and
- a resonant receive switch circuit coupled between the antenna port and the output port, said resonant receive switch circuit comprising a switch and an input matching circuit, wherein (i) said switch is ac coupled between the antenna port and the output port, (ii) when said switch is in a non-conducting state, a signal at said antenna port is passed to said output port, and (iii) when said switch is in a conducting state, the signal at said antenna port is reflected.
A transceiver low noise amplifier circuit comprising:
- an input terminal;
- and
- a resonant receive switch circuit configured to couple said input terminal to an input of the low noise amplifier, said resonant receive switch circuit comprising a switch and an input matching circuit, wherein (i) said switch is ac coupled between said input terminal and said input of said low noise amplifier, (ii) when said switch is in a non-conducting state, a signal at said input terminal is passed to said low noise amplifier, and (iii) when said switch is in a conducting state, the signal at said input terminal is reflected.
