RF Design Engineer

Our Hardware Team is seeking an RF Design Engineer. You would be responsible for designing and developing highly selective receive chains and 2-20 watt transmit chains for VHF, UHF, L, and S-band handheld and vehicular radios. TrellisWare’s products are engineered to provide robust and reliable communication in congested and contested RF environments.

Responsibilities

System-level RF design, including component selection and cascade analysis, using AWR Microwave Office; Component level design, leveraging integrated solutions but primarily focused on custom discrete filters and amplifiers; RF schematic entry (and ideally PCB layout) using Altium toolchain; Generate required design documentation; Validate and debug product performance through test and analysis at the component, module and system level; Collaborate with Product Management and Operations to carry development from prototype to production; Perform other duties as assigned

Requirements

Minimum Bachelor’s degree in electrical engineering or related field of study required; 5 years of experience with MSEE or 7 years of experience with BSEE as a RF/Wireless Design Engineer; RF cascade analysis and optimization for both noise figure and performance in strong interference environments; Filter synthesis and design, especially for low-loss, high power filters using lumped elements; Schematic entry and PCB layout experience (ideally using Altium tools); Linear RF simulation (ideally using AWR Microwave Office); Hands-on experience with RF circuit bring-up, troubleshooting, optimization, and high-volume production; U.S. Citizenship or Permanent Residency

Nice to have

Discrete amplifier design experience, particularly at 1 W and above; Understanding of both the features and limitations of integrated RF transceivers; Experience with non-linear simulations, including simulated load-pull analysis; Understanding of frequency conversion, frequency synthesizers, and PLL design up to 3 GHz with tight packaging constraints; Experience with EM Solvers such as HFSS, Momentum, Analyst or AXIEM (preferred); Work independently, demonstrate initiative and interact with a variety of engineering development teams; Demonstrate strong documentation skills and proficiency with PC office applications; Demonstrate analytical and problem-solving skills; Strong collaborative drive and interpersonal skills; Strong initiative, proactive work ethic and prioritization skills; Sound judgement and analytical problem-solving skills; Effective execution and decision making; Champion of change and promotes innovation; Strong written and verbal communication skills
