Abstract

An embodiment of the present invention provides an apparatus, comprising a radio frequency switch capable of using tunable dielectric capacitors as the switching element. The apparatus may further comprise a cross connector connecting a plurality of ports and wherein at least one of the tunable dielectric capacitors may placed between the cross connector at and least one port, thereby enabling impedance variations between the cross connector and the ports. Further, an embodiment of the present invention may provide at least one T connector between the cross connector and at least one of the plurality of ports, wherein at least one tunable dielectric capacitor may be associated with the T connector to vary the impedance in at least one node of the T connector.

Claims (8)

1. A method of switching radio frequency (RF) signals, comprising:

using at least one tunable dielectric capacitors as the switching element for an RF switch;

connecting a plurality of ports with a cross connector in said RF switch; and

enabling impedance variations between said cross connector and said ports by at least one of said tunable dielectric capacitors placed between said cross connector at and least one port.

2. The method of claim 1 , wherein said impedance variation enables RF signal control to any of said ports.

3. A method of switching radio frequency (RF) signals, comprising:

using at least one tunable dielectric capacitors as the switching element for an RF switch;

connecting a plurality of ports with a cross connector in said RF switch and placing at least one T connector between said cross connector and at least one of said plurality of ports, wherein at least one additional tunable dielectric capacitor is associated with said T connector to vary the impedance in at least one node of said T connector.
