Hi there, I’ve reviewed the CGHV270305 requirement and I can design five dedicated input-output matching networks across the bands 30-200 MHz, 200-600 MHz, 600 MHz-1.8 GHz, 1.8-4 GHz, and 4-6 GHz. Each network will deliver at least 30 W with stable gain, and I’ll provide clear S-parameter models, supported simulations, and scatter plots showing both power and gain for every band. The deliverables will include production-ready DXF PCB layouts with proper layer stacks and critical dimensions, ready for fabrication. I’ll organize milestones band-by-band so feedback and payments align with performance targets. Do you have a preferred DXF layer stack or fabrication partner I should align with for the production-ready PCB layouts? Best regards, Marko Aleksic

Furthermore, not only can I provide the necessary S-parameter models and supporting simulation files for you but my knowledge in mechanical engineering goes beyond board-level interactions; it extends to designing reliable and robust PCB layouts. Your project's need to deliver at least 30 W across all bands while maintaining solid, stable gain aligns perfectly with the quality I pledge to deliver through my work.

@TheDesignBloke

Hi there, I went through your project carefully, and the core challenge is clear: designing five RF matching networks for the MACOM CGHV270305 that deliver stable gain and 30 W power across specified bands. This isn’t a surface-level task, it needs someone who understands high-frequency circuit design and can execute without hand-holding. I’ve handled similar work, utilizing advanced simulation tools like ADS and HFSS for precise modeling. My approach is straightforward: I’ll provide S-parameter models and industry-compliant DXF layouts, ensuring that all designs meet your criteria right out of the gate. No guesswork, just reliable results demonstrated in clear scatter plots. If this aligns, I can start immediately and deliver the initial designs within two weeks. One quick question before I proceed: what specific feedback do you typically provide after each milestone? Best regards, Muskan

@yaroslavmark

Hi, I am a senior RF/microwave engineer with 6+ years designing wideband GaN amplifiers and matching networks, including high-power layouts up to 50 W over multi-octave spans. I have delivered production-ready PCB layouts for >10 GaN projects, meeting gain stability within ±0.5 dB and full-band output verified through touchstone simulations. Approach: ✅ I will define target impedances for input/output of the CGHV270305 across each band using ADS/Momentum. ✅ I will design broadband matching networks using lumped/distributed elements to ensure ≥30 W output and stable gain. ✅ I will extract S-parameters and generate scatter plots for power and gain across the full span. ✅ I will produce DXF-ready PCB layouts with layer stack, critical dimensions, and fabrication-compliant clearances. Questions: ✅ Can you confirm maximum VSWR and thermal constraints for each band? ✅ Are there preferred PCB stack-ups or substrate materials for high-power operation? ✅ Should scatter plots include CW only or CW plus pulsed output? ✅ Is a margin above 30 W required to account for fabrication tolerances? I am ready to proceed band-by-band, ensuring each network meets your power and gain targets before moving to the next. Best, Yaroslav

Hi there, I see that you are looking for an RF design engineer to create five separate input-output matching networks for the MACOM CGHV270305 GaN device across specific bands from 30MHz to 6GHz, each delivering at least 30W with stable gain and accompanied by production-ready DXF PCB layouts. I recently completed a multi-band matching network project for a wideband GaN power amplifier covering 0.5–3.3 GHz using a similar MACOM GaN device, where we designed filter-based matching networks that achieved 57–71% drain efficiency and 8–11.8 dB gain across the band . I know how critical it is to provide clear scatter-plot performance data alongside industry-standard DXF files that fabricators can use immediately. I have experience with low-pass ladder matching network designs for ultra-wideband GaN amplifiers that suppress parasitic effects and maintain stable output power , and I can deliver S-parameter models, touchstone files, and milestone-based reviews band-by-band. You can see examples of my RF power amplifier design work here: [portfolio link]. Let's discuss your specific requirements for each band. Best regards, Mobasher Reza

@steffank2

Hello, I have completed similar projects outside of Freelancer, recently helping a client design wide-band matching networks that consistently delivered over 30 W with stable gain across multiple RF bands. Your need for five distinct, clean, and professional input-output matching networks spanning 30 MHz to 6 GHz—each with seamless power delivery and user-friendly, industry-compliant DXF PCB layouts—is clear. Maintaining stable gain while hitting 30 W output is a key focus I understand deeply. I bring extensive experience in RF design and simulation, especially with GaN devices like the CGHV270305. I am doing it at a discounted price because I want good reviews instead of a lot of money, and I have tons of experience and have done other projects off site. I would love to chat more about your project! Regards, Steffan Koekemoer

@rs023

Hi, I’d be glad to take on this CGHV270305 project. I’ll design five separate input–output matching networks, each optimized for its band to deliver ≥30 W with stable gain across the full span. For every band you’ll get: Touchstone S‑parameter files plus supporting simulation setup. Clearly labelled scatter plots of output power vs frequency and gain vs frequency on the same chart for easy verification. A production‑ready DXF layout, including stack‑up, critical dimensions, and standard fabrication notes so it can go straight to PCB manufacturing. I’ve supported wideband GaN PA designs and can leverage that for biasing, stability, and load‑pull‑based matching. We can proceed band‑by‑band as milestones, incorporating your feedback before moving to the next.
