Hello so I thought I could use a VCO to generate a sine wave , but I didn't find anything that generates a sine wave with 500Khz. So then thought to use a microcontroller, like Atmel o Arduino, but it's really difficult to create a PWM greater than 4MHz. Anyway so now I am at a loss.
Does anyone know of any ways to make a sine wave? Please let me know what you think please.
