PROFESSIONAL EXPERIENCE:
Sr. RF Test Technician: CPC, Hauppauge, NY (DEC 2015 – MAY 2017)
Inspection, test, and alignment of all pulsed RF high power MRI modules for 3T and 8T systems from 100 thru 500 MHz using network analyzers, high voltage and current power supplies, and high power loads. Measurements included driver and power amplifier phase and gain linearity for amplifiers up to 2200 watts resulting in on time deliveries, improved quality and new orders.
Measurement of high power dual directional couplers, power dividers and combiners. Test and alignment of gain stability modules that adjust overall system gain over temperature variations.
Programmed and ran HASS and HALT screening and life testing on production modules.
Test and alignment of high current regulator modules employing bias, alarm, and over-voltage circuits. Regulator modules are interfaced with temperature compensation circuits.
Installation of programming software for the module embedded CPLD using the EPROM programmer station, for both XILINX and ALTERA integrated circuits.
Sr. RF Design Engineer: Frequency Electronics Inc., Uniondale, NY (FEB 2013 – OCT 2015)
Electromagnetic simulation of stripline couplers using Ansoft Designer7 EM software. Designs implemented in the microwave portion of the LO subsystem. Analysis of 2nd order phase locked loops for highly stable oscillators including damping and overshoot.
Designed, tuned and tested phase locked microwave oscillator systems, L band thru Ku band, both dielectric resonant and coaxial resonant, that included hybrid MIC and solder assemblies for space applications, resulting in increased shipments and new orders. Performed highly critical phase noise measurements of ultra - stable microwave sources.
Performed Microwave measurements at alignment and final test data stages using analyzers, chart recorders and temperature chambers for Boeing Aerospace WGS and IS - 29 thru IS –37 programs. Responsible for end package final data presentation to the customer and associated MS Excel .CSV data files and summary sheets. Generation of ATP procedures and datasheets for production use.
Design of Microwave test fixtures for production testing of hybrid MIC buffer, loop and output amplifiers. Generated mechanical drawing markups for immediate machine shop work orders. Full alignment and tuning on hot/cold plate configurations of dielectric resonator and coaxial resonator circuits, including frequency set, particle getter and burn-in.
Sr. RF Design Engineer: US Dynamics Corporation, Amityville, NY (NOV 2010 – NOV 2012)
Electromagnetic simulation of stripline couplers using Microwave Office AWR and Sonnet EM software. Designed high power coupler networks for a TARS radar transmitter, resulting in shipments and additional orders.
Performed design work on a radar reference antenna, which included printed phased array of dipole circuits and branch-line hybrid couplers resulting in reduced labor costs and saving considerable money.
Designed an X band ultra low noise 3 stage PHEMT amplifier with a built-in PIN diode attenuator and built in noise diode using Microwave Office. Obtained the device S-parameters supplied by the vendor and performed stability analysis. Designed PIN diode attenuator circuits for a microwave tone modulator and high speed AM modulator employing high power limiter diodes.
Sr. Electrical Engineer: MITEQ Inc., Hauppauge, NY (JUN 1987 – OCT 2010)
Extensive experience with frequency multipliers, mixers and oscillators, including the development and production of a new product line featuring low cost and repeatability. Developed multiplier products through Millimeter bands using commercial software packages including HPADS, Momentum, and Genesys, resulting in new orders.
Designed printed and mechanical filters, using Genesys, Momentum and other electromagnetic simulation programs, which included importing DXF files, adjustments in Autocad and setup in a Momentum context to produce artworks, photoplots, and laser etching files, with an emphasis on manufacturability.
Designed MIC hybrid amplifiers and multipliers using vendor supplied S–parameters and micro-miniature fabrication techniques. Designs were the results obtained in modeling from both Momentum and HPADS. The multipliers were shipped internationally, resulting in new customers.
Designed and tested K level space grade multipliers. Familiar with lot traceability, failure mode analysis, and data requirement lists (SDRL). Prepared all the analysis reports and element evaluation screening documents. The multipliers were delivered to Northrop Grumman Electronics Systems for launch as part of the NPOESS global satellite program.
