Strong background in circuit design fundamentals with ability to adapt to new material systems.
Experience with ADS and/or AWR Microwave Office for RF/analog design.
Understanding of RF/microwave circuit theory and system integration.

Nice To Haves

Experience with III-V material systems (GaN, GaAs).
Familiarity with parameter extraction, PDK development, or nonlinear modeling.
Proficiency in MATLAB, Python, or Verilog-A for simulation automation.

Responsibilities

Design RF switching and wideband linear amplifier circuits for sub-GHz to 10 GHz applications.
Apply CMOS switching or class D amplifier design principles to GaN-based architectures.
Utilize Keysight ADS and/or AWR Microwave Office for schematic, layout, and verification.
Contribute to parameter extraction, PDK optimization, and compact modeling.
Perform system-level analysis to define chip requirements and optimize performance.
Support design-for-test (DFT) and design-for-manufacturability (DFM) activities.
Work closely with Eridan’s GaN device design team and systems engineers.
Participate in design reviews and collaborate with foundry partners on material system integration.
Contribute to packaging strategies and digital/analog interface solutions.
