Job Title:   Senior Specialist, RF/Wireless Engineer

Job Code: 47504

Job Location: Carlsbad, CA

Job Schedule: 9/80: Employees work 9 out of every 14 days - totaling 80 hours worked - and have every other Friday off

Job Description: 

We are looking for a talented RF/Wireless design engineer with industry experience high power amplifier design. We design advanced wireless digital communication systems and electronic warfare systems.  Development efforts include the whole lifecycle of designs from proposals, requirement definition, simulation, synthesis, place and route, and verification testing.  We are looking for an engineer who enjoys challenging work with a team of talented engineers and can work well both with a team and as an individual contributor. San Diego provides incredible 365-day outdoor recreation options and cultural experiences, and L3Harris values your work/life balance so you can enjoy these opportunities.

Essential Functions:

• Develop high-power RF power amplifiers for fast-hopping military communications applications across L-band through C-band, with RF output power ranging from 8 W to 200 W.
• Evaluate, select, characterize, and model RF transistor and amplifier technologies, including GaAs HBT, GaN HEMT, CMOS, and SiGe.
• Design and simulate nonlinear, high-power RF systems using Keysight ADS and HFSS, including PCB parasitic extraction and electromagnetic analysis.
• Develop robust, temperature-compensated bias circuits and perform rigorous multi-loop stability analysis.
• Design complex wideband and multi-band matching networks using lumped and distributed elements.
• Support complete transmitter and receiver RF design, including power amplifiers, switches, filters, low-noise amplifiers, directional couplers, and limiters.
• Perform RF cascade analysis and assess overall system gain, noise figure, linearity, and performance tradeoffs.
• Collaborate with Systems, RF/Analog, Digital, and Firmware Engineering teams to integrate complete radio solutions.
• Lead lab bring-up, debug, characterization, and performance optimization using spectrum analyzers, RF signal generators, and network analyzers.
• Contribute to RF PCB layout, transmission-line design, analog circuitry, operational amplifier circuits, and basic switching power-supply design.
• Active US Secret security clearance

Qualifications:

• Bachelor's Degree in Electrical Engineering with a minimum of 6 years prior RF discrete power amplifier design experience. Graduate Degree in Electrical Engineering with a minimum of 4 years prior discrete power amplifier design experience. In lieu of a degree, minimum of 10 years of prior discrete power amplifier design experience.

Preferred Skills:

• Solid foundation in analog electronics, RF transmission lines and RF layout practices.
• Experience across the full high-efficiency PA development cycle, including device selection, evaluation and modeling, circuit design, linear and nonlinear simulation, PCB layout, EM/parasitic extraction, lab bring-up, debug, and optimization.
• RF design experience spanning approximately 0.9 MHz to 6 GHz, with a strong understanding of higher-frequency effects.
• Knowledge of RF device biasing, temperature compensation, RF dependencies, nonlinear behavior, compensation methods, and transmitter linearization techniques.
• Experience designing and integrating RF components including PAs, LNAs, switches, filters, couplers, and limiters.
• Experience with industry-standard RF design tools, including Keysight ADS and HFSS.
• Hands-on experience with RF test and measurement equipment, including spectrum analyzers, network analyzers, and RF signal generators.
• Switching power supply design
