Transmit the PWM signals through RFIC?

[ayush742]

I need to transmit a PWM signal wirelessly at 5 GHz and receive it at the other end. Could you please suggest any COTS devices available and provide any recommendations?

I read "pwm" as general digital signal. But which frequency, minimal and maximal pulse width? Required pulse width resolution and accuracy?
What's the intended RF channel? Free space, wave guide or cable? Restrictions regarding RF level and modulation bandwidth, e.g. due to radio regulations?

I am looking for this type of COTS module. Through which i can transmit the PWM signal.

• PWM Frequency: Likely in the kHz to MHz range, typical for IGBT gate driving.
• Minimal Pulse Width: Likely in the nanosecond (ns) range, given the 100 ns delay tolerance.
• Maximal Pulse Width: Likely up to microseconds (µs), based on typical gate control.
• Pulse Width Resolution: The system must have 100 ns resolution and high accuracy for real-time control.
• RF Channel: The primary RF channel is free space (5 GHz or 60 GHz wireless transmission).
• RF Level and Modulation Bandwidth: 9 GHz bandwidth (57–66 GHz), suitable for high-speed, low-power communication.

Latency, transmit measured digital value and reconstruct using PWM on sink side ? Or
would that latency be objectionable ? Is PWM source a baseband signal ?
