PROFESSIONAL EXPERIENCE
December 2016 – Present National Instruments Corporation, Santa Clara, CA
Senior RF/Microwave R&D Engineer
• Design, characterization and testing of microwave and millimeter-wave circuits and systems
o Currently participating in the design of an E-band automotive radar target simulation and testing system. Tasks include:
top-level and module-level system planning, analysis and design of mmw (76 – 80GHz, waveguide-type) circuits as well as the IF/LO (3 – 12GHz, on PCB), true-time delay and Doppler-shift subsystems used to generate static and moving artificial targets. Tasks included designing on-board reference generators (10/100 MHz), integrating microwave synthesizers and triplexers, planar and lumped-element filters, etc.
Writing LabVIEW code to program on board ADC, synthesizers, Digital steps attenuators, switches, etc. over an SPI interface.

Staff RF/Microwave R&D Engineer
• Design, characterization and testing of microwave and millimeter-wave circuits and systems
o Successfully contributed to the design of an E-band automotive radar target simulation and testing prototype
Tasks include top-level and module-level system planning, analysis and design of mmw (76 – 80GHz, waveguide-type) circuits as well as creation of a modular test radar unit at 76 - 80 GHz.
o Led the design effort of a Ka-band series of transceiver front-end systems (at 28.5 and 39GHz) for 5G communication applications
Tasks included system analysis, hardware and software (control and V&V using LabVIEW over I2C) design and mechanical module and housing design
Project management tasks included project scheduling, interfacing with system engineers, mechanical designers, hybrid assembly team, test technicians, assemblers and post-delivery integration support at the client site
o Participated in the development of a Ka-band (26.5-40GHz) down-converter extender front-end for spectrum analyzer solutions
Tasks included system level analysis, design of filters and R&D testing and implementing the complete V&V solution in LabVIEW to measure gain, harmonics and spurs using power meters, signal generators and spectrum analyzers
o Designed a 100GHz down-converter/up-converter single balanced mixer with an IF bandwidth exceeding 42GHz for the mmw down-converter front-end of a W-band real-time oscilloscope
o Participated in the design, integration and testing of a W-band front-end down-converter for a real-time oscilloscope
Tasks included module-level design (filters and amplifiers), system integration followed by testing to ensure compliance with system-level specifications followed by post-delivery integration support to clients
o Implemented a microwave test and characterization system up to 100GHz using LabVIEW and associated HF measurement hardware such as spectrum analyzers, frequency synthesizers, power meters and VNAs
June 2010 – April 2014 Phase Matrix Inc., A National Instruments Company, Santa Clara, CA
RF/Microwave R&D Engineer
• Participated in the design and characterization of a K-band wideband MMIC-based modulator
o Tasks included design and characterization of the microcircuit which had the modulator IC
Designs were completed using CST, AWR Microwave Office and LabVIEW for test routines.
o Designed filters, baluns and splitters up to 25GHz on alumina and Rogers 4000 series boards
o Implemented a test and characterization system for mm-wave W-band and V-band block down-converter systems to test the frequency response, spurious signals, harmonics, RF leakage, image rejection and other parameters using LabVIEW and instruments like spectrum analyzer, power sensors and frequency synthesizers amongst others
o Testing and characterization of a C-band radar altimeter by measuring pout, sweep-width, gain, MDS, etc.
o Characterization of in-house VCOs by checking for tuning sensitivity and phase noise
o Testing of a Ku-band oscilloscope front-end down-converter by measuring gain flatness at different power levels, 2nd harmonics, leakage, two-tone distortion, RF spurs and image rejection
o Proficient in the use of VNAs, SNAs, oscilloscopes, power meters and spectrum analyzers
o Completed National Instruments LabVIEW Core 1 and Core 2 training module
September 2009 – June 2010 Santa Clara University (SCU)
