Abstract
A Radio-Frequency (RF) circuit for an RF front-end includes a balanced amplifier with first and second amplifiers and an output directional coupler. First and second ports of the output directional coupler are coupled to outputs of the first and second amplifiers, a third port of the output directional coupler is coupled to an input-output terminal that is configured to be coupled to an antenna, and a fourth port of the output directional coupler is coupled to an input of a receiver amplifier. In a transmit mode, the output directional coupler may couple an RF signal to the input-output terminal. In a receive mode, the output directional coupler may couple a signal received from an antenna to the input of the receiver amplifier.
