90° RF Hybrid Coupler 18-40GHz 30W 2.92mm female 50ohm

Hybrid coupler is a passive RF component used in radio frequency (RF) and microwave systems to split or combine signals. It's essentially a four-port device where an input signal is divided between two output ports with a specific phase difference,

180˚ Hybrid Coupler is a coupler that splits an input signal into 2 output signals with equal amplitude and a phase difference of 180˚ between them. 

90˚ Hybrid Coupler is a 4-port directional coupler that equally splits an input signal with 90˚ phase difference between its output ports.

This phase difference, coupled with the equal power split, makes it useful for various applications like signal mixing, power splitting, and combining in amplifiers, switching circuits, and antenna beam-forming networks.
