Abstract
A transceiver includes an integrated circuit that enables board-level configuration of an on-chip or external transmit/receive switch. The transceiver uses a high-Q matching network, at least part of which is external, that improves receiver performance; increases transmit power while allowing for configuration of the same chip to use an internal TR switch, or external TR switch by changing connection at the board level rather than the chip level.
Claims20
A wireless communications transceiver, comprising:
- a transceiver integrated circuit comprising a transmitter with transmitter signal path and a receiver with receiver signal path;
- an antenna, external to the transceiver integrated circuit, selectively connected in a transmission mode to the transmitter signal path and in reception mode to the receiver signal path;
- and
- a high-Q matching network, comprising one or more elements external to the transceiver integrated circuit and connected between the antenna and the receiver signal path.
