Transmit-Receive Front End |
| 摘要 |
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. |
