Abstract:
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.
