I need help designing a UHF front end. Components include: 1) SAW filter 2) LNA 3) 4-way RF switch (solid state) 4) Some linear voltage regulator 5) Bias-T 6) Simple AGC circuit to avoid damaging/saturing receiver (similar to the one shown in this datasheet [login to view URL]) 7) Additional low pass filter from minicircuits I will need the schematic and board designed within one week, and prototypes in-hand by December 15. I would like you to have the boards professionally built, and tested for basic characteristics - insertion loss, noise figure, isolation, etc. I want you to send me three working prototypes. Prior to building, I want to review the schematic and PCB design. All components selected should be easily orderable from digikey.com. Don't bid on this project unless you have real experience with RF design. Send me examples of what you have designed. My budget includes PCB and components.

Hello, I have Masters Degree in Electronics, and about 8 years of RF design experience that includes ~30 RF PCB designs of various complexity (10s of components to 1000s) from IF up to 60 GHz. Please see some of my work on my profile. • I have used the following tools for PCB design, in order of preference: KiCad, Altium Designer 2014, PADS, Orcad, Eagle. • Have done full design cycle: proposal, specification, component selection, schematic, RF/System simulations, layout, ordering components, ordering PCBs, prototype debugging and testing with RF equipment such as: Signal generators, Spectrum Analyzers, NF meters, Network analyzers. Also have done callibration up to 60GHz. • Can diliver in 4 days: schematic, layout, simulation. • Manufacturing of 2 PCB prototypes: approx. 5-8 days. If comonents are hand/hot-plate solderable then 2-3 days limited by PCB manufacturing. • Testing: 1-3 days. ======== TOTAL: 7 - 18 days. Will try very hard to meet your deadline.

Hello, I am MS in RF/MW and we have more than 15 years experience in RF/MW system designing. I have already made a UHF system around 400 MHz including all the concerns. I can't send you the details due to confidentiality of project but rest assure we are professionals. I have 5 publications in international conferences. For the system design, we will provide you budget analysis using ADS to meet the desired NF, sensitivity, adjacent channel rejection and Dynamic Range etc I can better offer my services if you send me detailed product specifications. I can provide you design and PCBs in 2 weeks but fabrication can take time. We have access to noise figure meters, spectrum and network analyzers but that costs. If you can share the detailed specs, I'll give you a short analysis for free as confidence building measure. You will understand our capability once we discuss the details before rewarding the project. Hope to hear from you.
