Vetted SpecialistsExample profileLeila H.Principal RF Engineer, X-Band AESA RadarArchitected the T/R module and 4-channel beamformer for a 256-element X-band AESA — GaN PA at 38% PAE with 12 W per element, measured EIRP within 0.4 dB of prediction on the near-field rangeBuilt the array calibration method (mutual-coupling and phase-amplitude alignment) that took sidelobes from −22 dB to −31 dB and cut cal time per unit from 6 hours to 40 minutesChaired RF design reviews for a team of five and drove MIL-STD-461G RE102 and RS103 compliance on the first chamber campaignHFSS / ADSGaN PA designAESA calibration
Vetted SpecialistsExample profileDiego R.Senior RF Engineer, Ka-Band SATCOM TerminalsOwned the Ka-band front-end for a mobile SATCOM terminal: block up-converter, LNB and diplexer chain with 2.1 dB system noise figure and 62 dB transmit-receive isolation, qualified to MIL-STD-810HClosed the uplink and downlink link budgets against measured G/T and EIRP on a 1.2 m antenna, then validated over-the-air on a GEO carrier at 18 Mbps with 1.9% EVMRan DFM with the CM on the RF PCBs and machined aluminum housings, cutting first-pass tuning rejects from 30% to 5% across a 200-unit buildKa-band convertersLink budgetsMIL-STD-810H
Vetted SpecialistsExample profileRussell F.RF Engineer, Electronic Warfare and Counter-UASDesigned the 2–18 GHz wideband receiver front-end and jammer transmit chain for an airborne EW pod, hitting a 6 dB noise figure with 55 dB spurious-free dynamic range across the bandDeveloped the GaN PA driver and thermal design for a counter-UAS jammer, holding output flatness to ±1.5 dB over 400 MHz–6 GHz through a −40°C to +71°C profileLed anechoic-chamber and open-air range testing, correlating measured antenna patterns to CST models within 1 dB and writing the test procedures the program now uses for acceptanceWideband receiversCST / AWRAnechoic test
