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-precision 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 Operating frequency: 1-2.2GHz (actually measured 1-3GHz) Power supply: +5V single power supply Phase control: 1.4-358.6 Phase accuracy: 1.4 high precision Control mode: serial/parallel (default parallel control mode) Number of control bits: 8bit Transmission gain: -5 to +10dB (adjustable) The product appearance and printed words from batch to batch, but not affect the use Interface: SMA-K Colour:Black Material:PCB Package Contents: 1 x Phase Shifter Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
