Abstract: Presented is an interface circuit for connecting a RF antenna to a RF device. The interface circuit comprises: a first terminal adapted to connect to the RF antenna; a second terminal adapted to connect to the RF device; an inductive load connected to the second terminal; a first switch adapted to connect the inductive load to the first terminal; and a resistive load connected to the second terminal via a second switch.

Abstract: An RF switch for an RF splitter is disclosed, in which the bias voltage for the RF switching elements can be supplied, by using an RF to DC translator, from the RF signal on the input side to the switch. By using a native NMOS switch, routing of the RF signal is thus enabled without the necessity for an external power supply.

Abstract: A wireless transceiver comprising: a receiver adapted to receive signals in a television broadcast band; and a transmitter adapted to transmit signals in a different band. Also provided is a counterpart transceiver. The latter transceiver comprises: a transmitter adapted to transmit signals in a television broadcast band; and a receiver adapted to receive signals in the different band.

Abstract: The present invention provides a method and apparatus for compensating the output of a transmitter stage (50) of a communications system. A communications apparatus has a transmitter stage (50) providing a variable control voltage which varies the power of the transmitter stage. The impedance at the output of the transmitter stage. (50) varies as the power varies. A control generation circuit compares a reference voltage to the variable control voltage to produce a control signal (VvswrC). A compensated load (40) coupled to the output of the transmitter stage (50) has active component (s) whose' impedance varies in response to the control signal (VvsweC) so as to compensate for the impedance at the output of the transmitter stage (50).
