Hello, I’ve reviewed your goal to consolidate two RF transmit chains and an adapter into a single compact board while keeping the MYIR Zynq-7020 interfaces intact. My approach focuses on RF-aware layout, a shared reference clock with minimal routing changes, and off-the-shelf filters to shrink the bill of materials. I would deliver schematics and a manufacturable PCB layout that preserves I/O, uses modern LDOs, and provides flexible RF routing (combiner/splitter) without FPGA changes. What is the most critical constraint I should prioritize—preserving interfaces, minimizing FPGA changes, or manufacturability within JLCPCB/LCSC timelines? Best regards, Marko Aleksic

Hi, I’ve read your Zynq RF Board Size Reduction brief and I’m confident I can consolidate the two RF transmit paths and the adapter into a single compact board that keeps the MYIR Zynq-7020 interfaces intact and minimizes FPGA/software changes. I bring hands-on RF hardware design experience, tight RF/layout discipline, and practical manufacturing knowledge for JLCPCB/LCSC BOMs. My approach: map the current RF paths, share a robust reference oscillator/PLL, select compact off-the-shelf filters, and replace legacy regulators with small LDOs. I’ll design a compact RF-aware layout with clean routing, provide a single combined RF path with a splitter/combiner option, and ensure the design is manufacturable with minimal changes to the Zynq-7020 connections. The deliverables will include schematics, a production-ready PCB layout, a BOM aligned to JLCPCB/LCSC part numbers, and complete manufacturing files. I can start after NDA and share a phased timeline with milestones and daily progress updates. Please confirm the target frequency bands for both RF paths and any required isolation specs between paths. What is the preferred shared reference oscillator/PLL architecture (frequency, phase-noise targets, and jitter allowances)? How strict is the size constraint for the adapter board (approx. 2x2 inches vs. larger footprint)? Are there existing preferred LDOs or regulators you want to retire? Which RF outputs must be preserved as separate connectors for future tests, and should the spli

How do we consolidate your two RF TX boards and adapter into one compact RF aware board while keeping the MYIR Zynq 7020 interfaces unchanged and minimizing FPGA changes above 1 GHz performance intact. I have RF board design experience above 1 GHz and can own schematic layout and bring up with test access and validation hooks end to end. I have implemented shared reference clock and shared PLL architectures for multiple RF paths with careful clock distribution and phase noise protection practices. My RF mixed signal layout practices include partitioning continuous return paths controlled impedance routing via stitching isolation of LO and analog from digital and disciplined decoupling and grounding. I have done backward compatible redesigns where interfaces had to remain pin compatible and electrically equivalent to avoid firmware changes and I apply the same interface matrix approach here. I design for JLCPCB constraints and build LCSC based BOMs and I have replaced discrete filters with off the shelf RF filters and upgraded legacy regulators to modern low noise LDOs with noise filtering. I will deliver schematics RF aware PCB layout combiner and splitter routing options manufacturing ready files and an LCSC compatible BOM with clear availability and communication for long term work

Having tackled similar projects involving boards operating beyond 1 GHz, my role encompassed schematic design, meticulous PCB layout, and successful bring-up. I am well versed with leading low-cost fabs like JLCPCB and its BOM software. My knack for using LCSC compatible parts for efficient bills of material creation ensures that your output won't just work, but it'll work efficiently. By assigning me this project, you're not just availing of my technical proficiency in key domains like PLLs, filters, power decerebration etc., but also of my unrelenting dedication to delivering exceptionally crafted designs that withstand manufacturing scrutiny

@chuka8

I have hands-on experience designing RF boards above 1 GHz, including dual-channel transmit chains with shared reference clocks and PLL architectures. In a recent project (2.4 GHz ISM band), I handled schematic, RF layout, clock distribution, bring-up, and production release. Phase noise and isolation were managed through controlled impedance routing, solid grounding strategy, and careful PLL loop filter design. For your Zynq-7020 integration, I would consolidate both RF chains into a compact 4–6 layer RF stackup, implement a shared low-jitter reference with proper buffering, replace discrete filters with vetted LCSC SMD RF filters, modernize regulators using low-noise LDOs, and design configurable RF routing (combiner/splitter) with impedance-controlled traces. Interfaces to MYIR will remain electrically identical to avoid FPGA changes. I’ve delivered manufacturing-ready designs for JLCPCB using LCSC BOMs and understand their stackup, DFM, and component constraints. Estimated timeline: 4–6 weeks (schematic 1–2, layout 2–3, review & production pack 1). Estimated cost: $1,200 fixed (final quote after NDA + design review). Available ~25 hrs/week with structured weekly design reviews and documented progress.
