Hi, good afternoon, thanks for your post,
I am a graduated Electronics Engineer specializing in analog circuitry and PCB design having more than 8 years of experience in the field. I have read your entire description and your project perfectly suits my skills and expertise. I have designed sinewave signal generators using DSS IC (Direct Signal Synthetizers), such as the AD9833. Moreover, I have designed AB class output amplifiers up to 100KHz operating frequency. Finally, as per the power supply, we can use a power supply module, their are reliable, cheap and readily available.
I have a specific proposal of how to implement your system, kindly send me a message and let's discuss your project.
I detail below my skills related to this project:
* Analog circuit design and simulation using Spice based tools.
* Schematic and PCB design using KiCad, Altium designer, easyEDA and OrCad.
* Manufature files generation, familiarity with all the most common PCB manufacturers requirements and web interfaces.
* Power electronics, power supplies and output amplifiers.
Please send me a message so we can discuss this further, I look forward to your message, have an excellent day,
Regards,
