C-Band PA Design and Layout Using ADS Triquint's Library

Abstract
      The purpose of this exercise was to design a ¼ Watt C Band MMIC HPA utilizing Agilent/HP ADS software for eventual circuit fabrication by Triquint. Performance requirements were given for the design which included frequency range, gain, ripple, output power, and VSWR. Circuit layout was restricted to a standard 60x60 mil package. Class F operation was targeted for improved efficiency but was not realizable using standard Triquint elements within the allotted time. All other performance requirements were achieved using a two-stage design with Triquint GFET transistors. The complete design process included device selection, circuit design, circuit modeling and simulation, and physical layout. A test plan is included for testing of first unit to verify actual performance versus modeled performance.
