I am looking for a circuit developer who can create the following project. Ultrasonic nebulizer with 48V, 1,8A = 86W, 1,65MHz. Protection against overload 1.8A and thermal runaway typical of BJTs. Protection in case of transducer malfunction and/or short circuit. The dimensions of the board are 30x50mm, 30x75mm if required. There is an old CoolPits circuit that basically works, but needs some optimization. E.g. parallel operation of two transistors to compensate the power dissipation and counteract the thermal runaway typical for BJTs Protection against destruction if the transducer is shorted or missing. Schematic and EasyEDA/ Altrium file can be provided. Components should be as SMD. Driver is in THT. Any other idea is welcome. The result is what counts. Project has the following sequence: 1. you, circuit design and simulation 2. we, build the circuit on the fly and check the function 3. you, create PCB design and BOM list 4. we, manufacture the PCB A picture of the flying prototype is attached.

Hi. I will provide PCB for ultrasonic atomizer. In the process of PCB design, current overload, thermal protection, and short circuit protection will be considered, and defects existing in the existing Colpitts circuit will be eliminated and newly completed. A push-pull method is applied to improve the output efficiency, and SMT (surface attached) elements will be used. With reference to your schematic file for Altium Designer, I will design and simulate circuits and create PCB, GERBER, and BOM files. The created GERBER file will be supplied to the manufacturer and you will complete the device according to the BOM file. Hope your project is successful. thank you.

Hello there, I looked at the description of the project and it seems like your project is a great match for me since I have a lot of experience in PCB schematic and layout design. I have also looked at the pictures of your existing prototype and it confirms it should be no problem to do it. Just recently I finished the EMC immunity and emission seminar in Langer EMV, which consisted of many theoretical and practical examples which are helping in designing PCB layouts according to the best practices for best EMC and signal integrity compliant design. Please feel free to contact me to discuss further your requirements so I can give you my feedback about it. Also, I invite you to have a look at my profile and check my portfolio. I have the latest version of Altium Designer and it won't be a problem to deliver this project to you. Thanks and best regards.
