Hi there, I carefully reviewed your requirements and understand that this is an **existing multi-radio PCB** that already has the schematic, placement, and most routing completed, with the remaining work focused on RF layout correction, optimization, and final production readiness. I have experience with RF-aware PCB layout, multilayer stack-ups, 50-ohm controlled-impedance routing, antenna feeds, matching networks, return-path control, via stitching, RF keep-outs, grounding, EMI/EMC, and compact mixed-signal boards. I am also familiar with the types of RF sections involved here, including **Sub-GHz/LoRa, LTE, and GNSS**. I can review the existing KiCad design, correct and complete the RF routing, verify matching-network placement and grounding, check isolation between radios, review the stack-up and impedance assumptions, and complete the final DRC/DFM pass before fabrication. You will receive the finalized PCB source, Gerbers, drill files, and production outputs. I am also comfortable signing an NDA before receiving any proprietary design files. Just send me a message with the NDA and existing KiCad project, and I can start the review quickly. Best regards, Samuel tshibangu

Hi, I’m an experienced PCB Design Engineer with **15+ years of hands-on experience** in complex multilayer, high-speed, RF, communication, and embedded PCB design. Your project is a strong match for my experience. I can review the existing KiCad design, focus specifically on the **LoRa/Sub-GHz, LTE and GNSS RF sections**, and complete the remaining layout while preserving the existing architecture. I can handle: • 50Ω controlled-impedance RF routing • RF matching networks and antenna feeds • Ground returns and stitching-via strategy • RF isolation, keep-outs and EMI/EMC considerations • Multilayer stack-up and impedance review • RF layout corrections and optimization • Final DRC and manufacturability review • Production-ready Gerbers, drill files and fabrication outputs I’m comfortable working with existing proprietary designs and can proceed under NDA. I can first review the existing PCB and identify any RF/layout issues, then complete and verify the design for fabrication. I’d be happy to share relevant examples of my previous RF PCB work. Best regards, Ahsan

Hi, I’ve read the requirements carefully, and I actually just completed a similar RF PCB project involving LoRa/Sub-GHz, LTE/GNSS, 50Ω controlled-impedance routing, RF matching networks, antenna feeds, ground stitching, and RF keep-outs. So I’m familiar with the exact RF layout considerations you mentioned, including impedance control, RF grounding, isolation, and multilayer stack-up. I can review and finalize the existing design, complete the RF sections, perform DRC/DFM checks, and prepare the complete production-ready files. Please also check my portfolio for my previous PCB work. I’m comfortable working under NDA and ready to review the design once provided. Best regards, Ahmed

Hi, I’m an experienced PCB/Embedded Hardware Engineer with hands-on experience designing and reviewing multilayer PCBs in KiCad, including radio/RF hardware and a VoLTE telephony gateway. I have previously designed a radio PCB involving RF layout considerations, controlled-impedance routing, grounding, RF signal paths and production-oriented PCB design. I have also worked on a VoLTE telephony gateway, giving me practical experience with cellular/communication hardware and high-speed signal integrity. For this project, I understand that the schematic, placement and most routing are already completed. I can focus specifically on reviewing and completing the RF sections, including: • Sub-GHz/LoRa RF routing and layout • LTE and GNSS RF signal routing • 50Ω controlled-impedance transmission lines • RF matching network and antenna-feed layout • Ground return paths and stitching vias • RF keep-outs, isolation and layer strategy • EMI/EMC-aware layout • Stack-up and impedance considerations • KiCad DRC and fabrication-readiness review I can systematically review the existing PCB, identify RF/layout issues, make the required corrections, and take the board through final DRC and manufacturing checks, including Gerbers, drill files and other fabrication outputs. I’m comfortable working under NDA and understand the proprietary nature of the design. I’d be happy to review the existing board after the NDA and provide a clear assessment of the RF sections and remaining work.

Hello, I’m an Electronics Engineer with hands-on experience in PCB design, multilayer layouts, controlled-impedance routing and RF-aware hardware design. I’m interested in reviewing and completing your existing multi-radio PCB. I understand this is an existing design, so my focus will be on **RF layout finalization, correction and production readiness**, rather than redesigning the entire board. I can handle: • Sub-GHz / LoRa RF routing • LTE and GNSS RF layout • 50Ω controlled-impedance routing • RF matching network review • Antenna feed layout • Ground return paths and stitching vias • RF keep-outs and isolation • Multilayer stack-up review • EMI/EMC-aware layout • KiCad DRC and design-rule verification • Manufacturability and fabrication review • Final Gerbers, drill files and production outputs My approach is to carefully inspect the existing stack-up, RF signal paths, matching networks, antenna interfaces, ground continuity and isolation between radio sections before completing the remaining routing. I’m comfortable working under NDA and handling proprietary hardware information confidentially. Once the design files are available, I can review the PCB, identify RF/layout issues, implement the required corrections and deliver a clean, fabrication-ready KiCad project and manufacturing package. I’d be glad to discuss the board architecture and RF requirements after the NDA.

Hi, RF performance is often determined by the details that remain after the main PCB routing is finished—50 Ω transitions, return paths, matching networks, ground stitching, antenna feeds, and isolation between radios. This is exactly the stage where I can help bring your existing design to production readiness. I have hands-on experience with multilayer RF PCB layout, controlled-impedance routing, antenna interfaces, RF matching networks, stitching vias, ground-plane management, and EMI/EMC-conscious routing. I am comfortable working with LoRa/Sub-GHz, LTE, and GNSS sections and understand the specific layout requirements of each. I can review the stack-up and impedance requirements, complete and correct the RF routing, verify antenna feeds and matching networks, optimize RF return paths and via fencing, check RF keep-outs and radio isolation, and perform the final DRC and manufacturability review. You will receive the completed KiCad PCB, RF layout corrections, impedance and grounding review, matching-network review, final DRC, Gerbers, drill files, and production-ready fabrication outputs. I understand the proprietary nature of the design and am comfortable working under NDA. Send me the NDA and the existing PCB requirements/files—I am confident I can identify and resolve the remaining RF layout issues and get this board ready for fabrication. Best regards, António

@HeyAbhinav

Greetings, As it requires RF layout, I'd like to first review the existing layout to have a closer look at the planes and component placements. Do let me know what materials are you looking into for the substrate and the copper weight of inner and outer layers. Also is it HDI or normal 4-layers stack? I see we've a proprietary design here and that's a good thing to sign an NDA beforehand. The single-ended 50 Ohm controlled-impedance RF routing is industry standard for most RF designs and will be implemented. I'll personally review the design for DRC/DFM and will recommend any enhancements needed. I believe my work is to take you from incomplete design to a production-ready design, and that will be served. Just type a "Hi" to me and there we go... Best Regards!
