Abstract
A wireless apparatus comprising: i) an intermediate frequency (IF) unit configured to transmit and to receive IF signals; and ii) a radio frequency (RF) unit configured to transmit and to receive RF signals via an antenna and to receive IF signals from the IF unit and to transmit IF signals to the IF unit. The RF unit comprises: iii) a first sensor coupled to a first port of the RF unit, wherein the first sensor is configured to determine whether an incoming IF signal transmitted by the IF unit is present on the first port; and iv) a first transceiver configured to be controlled by the first sensor. The first transceiver is switched to transmit mode in response to the first sensor determining that an incoming IF signal is present on the first port.

A wireless apparatus comprising:
- an intermediate frequency (IF) unit configured to transmit and to receive IF signals;
- and
- a radio frequency (RF) unit configured to transmit and to receive RF signals via an antenna and to receive IF signals from the IF unit and to transmit IF signals to the IF unit, wherein the RF unit comprises:
- a first sensor coupled to a first port of the RF transceiver unit, wherein the first sensor is configured to determine whether an incoming IF signal transmitted by the IF unit is present on the first port;
- and
- a first transceiver configured to be controlled by the first sensor, wherein the first transceiver is switched to transmit mode in response to the first sensor determining that an incoming IF signal is present on the first port.
