Provide RF/Microwave engineering expertise and consulting services to client companies.

Facilitated the interface of photonic devices (LASERs and photo detectors) with RF components for high frequency fiber optic communications that utilize analog and digital links. Modeled RF circuits with photo detectors using HFSS at frequencies up to 25GHz. Laser characterization included RIN, power, wavelength, and spectrum analysis.

Responsible for first article manufacturing of W-Band antenna and servo assembly, coordinate engineering and manufacturing resources through procurement, fab, assembly, integration and top assembly test. Provided and carried out systems specification for Satellite Communications project.

CEO and Founder of Elite Systems Corporation with over 18 years experience in design, fabrication, integration and test of components and subsystems operating at frequencies from 80 MHz to 100 GHz. Provided guidance for teams transitioning products from engineering to production. Supported issue resolution of production anomalies. Supported bid and.

Established and directed proprietary microwave lab in accordance with requirements for antenna and missile seeker research & development. Supported research into phased array transmit/receive (T/R) modules, antenna design, RF systems, and fabrication / measurement of microwave and millimeter-wave components. Measurements included NF, P1db, IP3, Gain.

Designed, synthesized, and developed requirements for hardware systems, subsystems, and components. Provided technical support and issue resolution for PAC3 (Patriot Advanced Capability) manufacturing and production areas. Carried out subsystem and component design for Ka-Band(30GHz), V-Band(60GHz) and W-Band(100GHz) industrial research and development.

Carried out system integration and test of wireless transceivers. ASIC controlled digital spread spectrum technology was used for transmitters and receivers operating at RF frequencies below 2.5GHz.Selected Projects & Accomplishments at Boeing Facilitated 12% profit for L-Band Transceiver program as new Lead System Integrator and accelerating delivery.

Developed 1GHz - 20GHz software controlled Test Equipment Synthesizer. Hardware and circuit design tasks include Voltage Controlled Oscillators (VCOs), Phase Lock Loop (PLL) Synthesizers, active multipliers, amplifiers and filters. Microstrip and co-planar waveguide technology used on substrates.

Carried out RF engineering of radar components. Designed combination transmit/receive L-Band Switch Low Noise Amplifier for phased array radar receiver front end, operating in four-kilowatt high power pulsed RF environment.

Performed and directed RF and microwave design, test, and fabrication at Torrance Research Center. Served as Project Manager and Project Engineer on complex, mission-critical projects.  Managed $500,000 IR&D project to design and fabricate 20GHz thermo-electrically cooled low noise amplifier. Supervised up to five direct reports. Contributed to 5% sales.

 Responsible for RF design, fabrication and test of crystal controlled oscillators, RF power amplifiers and frequency multipliers (active and passive). This was part of a design effort for the solid state local oscillator (SSLO) subsystem of the Navy Standard Missile. This project was part of a major redesign of the SSLO. Only 15 months was allocated from.
