摘要： The present invention discloses a transmit-receive (TR) front end. The TR front end includes a low-noise amplifier (LNA); a power amplifier (PA); a transformer, coupled to the PA, for increasing a voltage swing and a power transmission of the PA; and a TR switch, coupled between the transformer and the LNA. The LNA is single ended and there is no transformer between the LNA and the TR switch.

摘要： A radio transceiver is disclosed. The transceiver comprises an integrated circuit. The integrated circuit comprises a transmit path; a first switch coupled in series with the output of the transmit path; a receive path; and a second switch coupled as a shunt with the input of the receive path. The transceiver further comprises a plurality of external matching networks coupled to the transmit and receive paths of the integrated circuit to ensure minimal loading from one path to the other. The transceiver also comprises a shared balun for converting differential signals from the plurality of external matching networks to single ended signals; and an antenna to interface with the single ended signals. A method and system in accordance with an embodiment enables tying together the transmit path and the receive paths of a radio transceiver without the need for an external T/R switch. A method and system in accordance with an embodiment minimizes the loading effects between the transmit path and the receive path such that output power and NF noise figure are not degraded after tying the transmit path and the receive path together.
