WORK HISTORY
Senior Rfic Design Engineer and Team-lead @Dover Corporation
Tampa, FL, US
Design mm-wave, Ka-band, Ku-band, X-band, C-band, and S-band GaN HEMT, GaAs pHEMT PAs, LNAs, switches, FEMs, filters, MCMs, and RF PCBs. Design for satcom, aerospace, defense, and cellular markets-Coordinate with marketing, production, assembly, packaging, and foundry counterparts to release successful MMIC/RFIC, and RF multi-chip module products on-time, under-budget, and with first-pass success-Use AWR Microwave Office, AWR Analyst, and Keysight Genesys to design MMICs/RFICs and RF PCBs-Designed and taped-out 26.5-30.5 GHz three-stage class-AB NGC GaN PA for satcom and military radar applications. Achieved 24 dB small-signal gain, 31% PAE, 45 dBm OIP3, 37 dBm OP1dB, and 17 dB I/O return loss all with < 5 W/mm dissipated power in all devices-Designed and taped-out 26-32 GHz TDD NGC GaN FEM for 5G cellular, comprised of 5 W, three-stage class-AB PA, three-stage high-linearity LNA, and compact, low-loss SPDT. In TX-mode, achieved 22.5 dB small-signal gain, 28% PAE, 44 dBm OIP3, 36 dBm OP1dB, and 17 dB I/O return loss, with < 5 W/mm dissipated power. In RX-mode, achieved 21 dB small-signal gain, 32 dBm OIP3, 22 dBm OP1dB, and 15 dB I/O return loss-Designed and taped-out 60-65 GHz 2 W MMIC PA in 90 nm GaN process as part of Starry Nite MPW program-Designed and taped-out 31-38 GHz, 10 W, two-stage Ku-band class-AB MMIC PA in BAE GaN process-Designed and taped-out both 8-pole and 4-pole (for each band) 2-4.5 GHz, 12-15.5 GHz, and 15-18.5 GHz low-loss, high-rejection Win GaAs MMIC elliptic bandpass filters for both standalone use and incorporation into a switched-fixed-filter bank MCM PCB-Designed and oversaw fabrication of 2-18.5 GHz switched-fixed-filter bank multi-chip module PCB on two-layer Rogers RO4350B, using above filters-Designed 3x3 and 4x4 QFN MMIC evaluation RF PCBs on Rogers RO4003-Designed and taped-out 12-18 GHz two-stage, 2W reactively-matched, high-power Win MMIC GaN LNA with 1.45 dB NF, 17 dB small-signal gain, and 43 dBm OIP3

ABOUT ALEXANDER C.
Senior RF design engineer/team-lead, engineering project manager, and applied physicist passionate about innovating at established technology companies with impactful missions as well as starting lucrative tech ventures that drive positive societal change. Good at solving complex physics and engineering problems by reasoning from first principles and thinking outside the box to ideate innovative solutions. Passionate about designing cutting edge mm-wave RFICs, MMICs, and analog/mixed-signal ICs and PCBs as well as spearheading state-of-the-art NPI initiatives for 5G, satcom, defense, and IoT products.“Everything around you that you call life was made up by people that were no smarter than you. And you can change it, you can influence it, you can build your own things that other people can use.(…) The most important thing is to shake off this erroneous notion that life is just there and you’re just gonna live in it versus embrace it, change it, improve it, make your mark upon it — and once you learn that — you’ll never be the same again.” —Steve Jobs“He not busy being born is busy dying.” —Bob Dylan
