Abstract
An embodiment of the present invention provides an apparatus, comprising a filter; and a matching network coupled to the filter, the matching network including a plurality of voltage tunable dielectric varactors.
Claims6
An apparatus, comprising:
- a filter;
- an automatic adjusting a matching network coupled to said filter, said matching network including a supported by a low-loss, non-tunable dielectric substrate which in turn is supported by a first ground conductor and includes at least one conducting partial-stage supported by a low-loss voltage-tunable dielectric layer, which in turn is supported by a second ground conductor, and
- an adjustable DC voltage source supplied to said filter and said matching network, wherein said adjustable DC voltage source is used to supply bias voltage to said matching network and said filter in tandem.
A method, comprising:
- using a filter;
- coupling an automatically adjusting matching network to said filter, said matching network supported by a low-loss, non-tunable dielectric substrate which in turn is a supported by a first ground conductor and includes at least one conducting partial-stage supported by a low-loss voltage-tunable dielectric layer, which in turn is supported by a second ground conductor;
- and
- supplying an adjustable DC voltage source to said filter and said matching network, wherein said adjustable DC voltage source is used to supply bias voltage to said matching network and said filter in tandem.
