    摘要: A transceiver 400 is provided in an ultrawide bandwidth device, which includes an antenna 110, a transmitter circuit 145, and a receiver circuit 165. A transmitter amplifier 440 is provided between the antenna 110 and the transmitter circuit 145, and is configured to have an operational transmitter output impedance when the transceiver 400 is in a transmit mode and an isolation transmitter output impedance when the transceiver 400 is in a receive mode. A receiver amplifier 460 is provided between the antenna 110 and the receiver circuit 165, and is configured to have an operational receiver input impedance when the transceiver 400 is in a receive mode and an isolation receiver input impedance when the transceiver 400 is in a transmit mode. The isolation transmitter output impedance is greater than the operational receiver input impedance, and the isolation receiver input impedance is greater than the operational transmitter output impedance. Thus, a transmitter and receiver can be isolated without using a transmit/receive switch.
