Description

The RTR series of Doppler Radar Receiver was developed by RTI to measure the Doppler phase shift (I/Q Outputs) and intensity (Log output) in Radar applications.

Design Note: Radar Technology can customize any of our products to meet your individual system requirements. RTI also offers many Form, Fit, Function replacements to old RHG Electronics Amplifiers.
