Abstract: The present invention discloses a transmit-receive (TR) front end. The TR front end comprises 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 to the transformer at a first end and coupled to the LNA at a second end, wherein the second end is capable of being coupled to an antenna; wherein the LNA is single ended and there is no transformer between the LNA and the TR switch.
Abstract translation: 本发明公开了一种发射 - 接收（TR）前端。 TR前端包括低噪声放大器（LNA）; 功率放大器（PA）; 耦合到PA的变压器，用于增加PA的电压摆幅和电力传输; 以及TR开关，其在第一端处耦合到所述变压器，并且在第二端处耦合到所述LNA，其中所述第二端能够耦合到天线; 其中LNA是单端的，并且LNA和TR开关之间没有变压器。
