RF/Microwave Modules Engineer
Location:
Libertyville, IL On-site
Company:
SuperApex LLC
Position Overview We’re seeking an experienced
RF/Microwave Modules Engineer
to lead the design, development, and testing of high-frequency integrated modules and subsystems. The ideal candidate will have a solid foundation in MMIC integration, packaging, and RF performance optimization across the ~0 GHz – 65 GHz range.
Key Responsibilities
Design and develop
RF/Microwave modules
integrating MMICs, passive components, and antennas.
Lead the
design, layout, and packaging
of RF front‑end assemblies, including Antenna‑in‑Package (AiP) and System‑in‑Package (SiP) architectures.
Perform
RF simulations and circuit optimization
using Keysight ADS, HFSS, and similar tools.
Collaborate with mechanical, process, and test engineers to ensure electrical, thermal, and mechanical integrity.
Conduct
VNA, spectrum, and power measurements
to characterize performance and validate designs.
Develop test plans, procedures, and documentation consistent with
ISO 9001
standards.
Support new product introduction (NPI) from prototype through production.
Required Qualifications
B.S. or M.S. in Electrical Engineering, Microwave Engineering, or a related field.
3+ years of experience in RF/Microwave module or subsystem design.
Proficiency with
Keysight ADS ,
HFSS , or
CST
for circuit and EM simulation.
Hands‑on experience with RF test equipment: VNA, spectrum analyzer, power meters, and noise figure analyzer.
Understanding of
impedance matching, bias networks, and amplifier design
(LNA, driver, PA).
Experience with
GaAs/GaN MMICs , hybrid modules, or multi‑chip packaging.
Preferred Qualifications
Experience with
Antenna‑in‑Package (AiP)
or
module‑level integration .
Familiarity with
III–V semiconductor processes
(GaAs pHEMT, GaN HEMT).
Knowledge of
thermal management, interposers, and RF substrates
(AlN, Rogers, etc.).
Experience with high‑frequency test automation using
Keysight PathWave, BenchVue , or LabVIEW.
Familiarity with
ISO 9001
workflows and documentation.
Excellent communication and problem‑solving skills, with the ability to collaborate across global teams.
Why Join SuperApex
Work on next‑generation
5G and 6G RF modules
with real‑world impact.
