Abstract
A transceiveris provided in an ultrawide bandwidth device, which includes an antenna, a transmitter circuit, and a receiver circuit. A transmitter amplifieris provided between the antennaand the transmitter circuit, and is configured to have an operational transmitter output impedance when the transceiveris in a transmit mode and an isolation transmitter output impedance when the transceiveris in a receive mode. A receiver amplifieris provided between the antennaand the receiver circuit, and is configured to have an operational receiver input impedance when the transceiveris in a receive mode and an isolation receiver input impedance when the transceiveris 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.
