Abstract

The apparatus includes a first transistor having a gate/base terminal to receive a first drive control signal used for controlling a driver stage of the transceiver and a drain/collector terminal coupled to a control terminal of a switch of the transceiver. The first transistor is switched on when the first drive control signal is at a first level that enables the driver stage to amplify a first RF signal. When the first transistor is switched on, the drain/collector terminal of the first transistor outputs to a control terminal of the switch a switch control signal at a second level that enables the switch to provide a portion of the RF signal reflected by the antenna to the load.
