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.
