433 MHz Antenna Switch Review

I need an RF engineer to review an existing RF schematic for a 433 MHz / 470 MHz shared-antenna switch design. The current schematic already includes the main RF chain components, and I need someone to verify the design before schematic lock. Scope of Work: -Review the current RF schematic for the 433 MHz / 470 MHz shared-antenna switch design. -Check the switch logic around the SKY13405-490LF RF switch. -Review the detector path using the MAX2204. -Check the amplifier stage using the MGA-53543. -Review the existing BPF-C495+ filter chain. -Build an initial RF simulation plan in Keysight ADS. -Verify expected RF performance, including: -Use datasheet models, S-parameter files, or equivalent RF block models where available. -Propose practical corrections before the schematic is finalized. Expected Deliverables: -Reviewed schematic notes and comments. -Initial ADS simulation plan. -RF performance expectations and risk areas. -Practical correction suggestions before schematic lock. The ideal candidate should have experience with RF circuit design, RF switches, filters, low-noise/amplifier stages, RF detectors, S-parameter simulation, and ADS. Please apply only if you have practical RF design and simulation experience, especially around sub-GHz RF systems.
