Notes
Design 30W QPSK linear 2.3 GHz GaAs FET Power Amplifier & ALC circuitry to hold power output
within +/- 0.05 dB for a space application. Design X-Band FET Power Amplifiers, and retro-fit earlier
bipolar power amplifiers.
Medical Optics, Inc., Carlsbad, CA
Design of a 1200 W Pulsed Oscillator / RF Driver / Amplifier to excite a medical laser. Prepared complete
documentation package, consisting of detailed circuit schematics, parts lists, and mechanical housing
drawings.
Quest Technology Inc., Carlsbad, CA
System design and hardware development of Fiber Optic Antenna Remoting Systems for use in the 5 MHz
to 12 GHz SATCOM range for GPS, INMARSAT, and SATURN.
ADX Microsys Corp., Los Angeles, CA
Design of "chip & wire" linear Power Amplifier circuits at 800-950 MHz, and 1.8, 2.4, and 5.7 GHz, for
use in a wide variety of cellular, PC's, WLAN, and other RF applications.
Jet Propulsion Laboratory / NASA., Pasadena, CA
Performed highly detailed worst case and RSS transmit power and receiver gain uncertainty calculations.
Designed thermal-vac test system for NASA NSCAT Ku-Band Orbital Scatterometer.
Design, fabricate, and test 64 Watt Pulsed C-Band GaAs FET Power Amplifier for use on SIR-C
(Spaceborne Imaging Radar - Model C), similar to that used by the Magellan Venus probe which flew
in 1993. This flight discovered the crater of the comet in Yucatan thought responsible for the extinction
of the dinosaurs, and the Lost City of Ubar in the arabian desert.
Design of highly sensitive low-noise microwave receivers for the worldwide Deep Space Network (DSN)
Voyager spacecraft tracking system.
Design Engineer for NASA NSCAT Ku-Band Orbital Scatterometer Ground/Flight TX/RX Test System.
The satellite was placed on-orbit in 1995 by the Space Shuttle.
Hughes Aircraft Co., Newport Beach, CA
Design of X-Band hybrid MIC PIN diode switches and "chip & wire" switch drivers. Produced PCB "camera
ready" artwork using own software tools.
