Wi-Fi HaLow MM6108 PCB

I’m building a telecommunications-grade remote-monitoring node that must use Wi-Fi HaLow in the sub-1 GHz band. The heart of the design is the MM6108 transceiver, paired with an on-board band shifter rffc5071 so the radio can stay well inside the regional ISM allocation while preserving link budget and sensitivity.

Your task is to take the concept from schematic to production-ready PCB, paying close attention to controlled-impedance routing, power-supply decoupling, ground referencing, and the filter network around the MM6108. I expect you to choose stack-up, define the antenna interface (chip, whip, or SMA—please advise), and validate the RF path with simulation or VNA measurements so we know the board will meet FCC requirements before we order prototypes.

Deliverables
• Complete schematic and PCB layout in Altium or KiCad or diptrace
• Gerber/ODB++ files, fabrication notes, and pick-and-place data
• Bill of materials with part numbers in current distribution channels
• Brief tuning report showing how the band-shifter network meets the sub-1 GHz target

I’m ready to answer mechanical or enclosure questions right away and can provide test-bench time once the first spin is in hand. If you have recent HaLow, Sub-1 GHz, or similar RF work in your portfolio, I’d love to see it alongside your proposal.
