Transmitting high-speed PWM over RF

[White, Joshua J]

First, let me apologize in advance if this isn't the correct forum for this question.

 

I have a 50 MHz PWM signal (it's actually a 50 MHz 50% DC clock with a 1PPS clock embedded with PWM) that I would like to transmit over the 2.4 GHz ISM band with as low latency as possible. My original thought was to digitize the clock with a high-speed ADC, then stream the samples to GNU Radio and transmit via SDR, then recover on the receive side and playback the samples with a high-speed DAC. The problem I'm running into is that the only capture cards I've been able to find capable of running at the sample rate needed (>500MS/s) and streaming in real-time to GRC are prohibitively expensive ($8000+).

 

My question is, is anyone aware of any alternative methods of transmitting the 50 MHz PWM over ISM? I would be willing to entertain a different method of streaming to GRC or an entirely different setup. I don't know of any radios that could take the signal as input directly and transmit it, then receive it and output it directly, but admittedly I am rather new to the world of RF so it's possible there's a solution that exists that I'm simply unaware of.

 

Very respectfully,
