Abstract:
1. A transceiver for use in a wireless device, comprising: a transmitter circuit configured to generate a wireless signal for transmission; a transmitter amplifier connected between the antenna and the transmitter circuit, the transmitter amplifier configured to have an operational transmitter output impedance when the transceiver is in a transmit mode and an isolation transmitter output impedance when, the transceiver is in a receive mode; a receiver circuit configured to receive and process a wireless signal received at the antenna; a receiver amplifier connected between the antenna and the receiver circuit, the receiver amplifier configured to have an operational receiver input impedance when the transceiver is in a receive mode and an isolation receiver input impedance when the transceiver is in a transmit mode, wherein the isolation transmitter output impedance is greater than the operational receiver input impedance, and wherein the isolation receiver input impedance is greater than the operational transmitter output impedance.
