1. A transceiver comprising:
- a first node for receiving a received signal and transmitting a transmitted signal;
a receiver, connected between a first voltage and the first node, for processing the received signal;
a transmitter, connected between a second voltage and the first node, for generating the transmitted signal; and
a DC voltage controller for at least one of;
selectively activating at least one of the transmitter and the receiver; and
selectively substantially deactivating at least one of the transmitter and receiver.
