Radio Frequency Power Circuits Utilizing Coaxial Resonators for Video Bandwidth Improvements and Circuit Size Reduction and a Process of Implementing the Same

Abstract:

A packaged RF power amplifier (RFPA) configured to increase video bandwidth is disclosed as well is a process for implementing a RF power device to increase video bandwidth. The RF power device including at least one transistor; an output matching circuit coupled to an output lead and to the at least one transistor; at least one bias feed circuit coupled to the at least one transistor; and at least one coaxial resonator coupled between the at least one transistor and the at least one bias feed circuit.
