Abstract

A ferro-electric tunable duplexer is provided, integrated with one or more of the following parts: a power amplifier, an isolator, a diplexer, a low noise amplifier and an antenna matching circuit. More specifically, in addition to adding F-E tunability, one or more of the above components is integrated with the duplexer on one substrate. The components are integrated on one substrate either by placing each component, with the appropriate matching circuit directly on the substrate, or by direct fabrication of the component and matching circuit into or onto the substrate.
