[Hackrf-dev] Beam Steering Using Hackrfs

Hi all,

I will attempting to create a beam steering lab using Hackrfs and I wondered if anyone had any experience/advice in this area.

We would like to create a 4 element linear array driven by Hackrf s. To beam steer we need to be able to control the phase and amplitude of the 4 elements. Usually we would use a phase shifter and an attenuator.

However, since we will be using Hack RF for the baseband we were wondering if there was a way to use them for the RF control as well.

Many thanks

Robert.
