Koolenry 1-2.2GHz 8bit Phase Shifter Digital Microwave Phase Shifter Control Board for Signal Radar Communication Radio

Phase shifters are devices that control signal phase changes and are widely used in radar systems, microwave communication systems, and measurement systems This module uses digital program control technology to achieve input signal phase changes. The frequency range covers 1-2.2GHz, and the actual measurement is suitable for 1-3GHz 8-bit serial or parallel control is used to meet high- requirements, with a minimum phase shift step of 1.4 degrees; at the same time, the module has a built-in preamplifier, which makes up for the signal attenuation caused by the insertion loss of the digital phase shifter
