7 GHz Synthesizer PCB Design -- 2

I already have the PLL/VCO core defined—our board will lift that portion straight from the Analog Devices ADF4372 / ADF4356 evaluation schematics—so the real task lies in crafting the 7.0 – 7.5 GHz output chain and turning the whole concept into a manufacturable four-layer Rogers 4350B PCB inside Altium Designer. The RF path needs to be clean, 50 Ω, and production-ready, with any filtering, buffering, or gain-staging you judge necessary to deliver a spectrally pure, repeatable signal. All the usual high-frequency layout disciplines apply: controlled-impedance traces, via fencing, tight reference-plane management, and rigorous power-supply decoupling. On top of that, I have three non-negotiables for the layout: • Thermal management for the PLL, VCO, and any active output-chain parts • Proven signal-integrity practices from the VCO pads right out to the SMA edge launch • Solid power-delivery design so the synthesizer meets phase-noise specs across load and temperature Deliverables I will review and sign off on: • Complete Altium Designer project (schematic, PCB, libraries) • Clearly annotated RF output-chain schematic with component values, footprints, and reference design equations • Final Gerbers, drill files, and stack-up notes for Rogers 4350B fabrication • BOM with manufacturer part numbers and at least one in-stock source per item • Brief design report summarising key calculations, simulated S-parameters, and expected output power/phase-noise performance I will handle final bench validation; your design should be ready for turnkey fab and assembly. If you have any questions about board size, connector orientation, or test points, just let me know and we can lock those details in early.
