摘要： A radio frequency (RF) front end circuit includes a transformer coupled to a switch. The transformer converts a balanced transmit signal to an unbalanced transmit signal and converts an unbalanced receive signal to a balanced receive signal. The switch is configured to operate in first and second states. In the first state, the switch receives the unbalanced transmit signal from the transformer and transfers the unbalanced transmit signal to an amplifier and receives an amplified transmit signal from the amplifier and transfers the amplified transmit signal to a band pass filter. In the second state, the switch receives a filtered receive signal from the band pass filter and transfers the filtered receive signal to the transformer.
