Automotive GPS/Digital Radio LNA Review

RF engineer wanted for independent review of automotive GPS + digital radio LNA I have an existing RF/LNA design for an automotive application with two frequency paths: GPS and digital radio. I am looking for an experienced RF engineer to perform an independent critical design review, rather than redesigning the circuit from scratch. Main areas to review: RF architecture and signal paths Input/output matching networks LNA biasing and stability Gain and noise figure Filters and LC networks Isolation between GPS and digital-radio paths PIN diode implementation RF input protection Strong-signal behaviour and potential saturation/intermodulation Supply decoupling and grounding PCB layout recommendations Component selection and tolerances Expected deliverable: a concise technical report identifying potential problems, their severity, recommended changes, and measurements/simulations required to validate the design. Please apply only if you have practical RF hardware experience. In your proposal, briefly describe previous LNA/GNSS/RF front-end designs and the RF measurement equipment you have used (VNA, spectrum analyser, noise figure measurement, etc.).
