Low PIM 698-2700MHz 4x4 hybrid matrix 4 in 4 out rf cavity hybrid coupler DIN connector hybrid combiner

Description.

The hybrid coupler is a kind of passive component used for in-building solution, used for the same frequency combination. The main function is to combine the two transmitting and receiving ports of the base station into one, and the signal is combined into one to connect to the repeater host. The 3db coupler is also called the same frequency combiner, which can divide an input signal into two signals with equal amplitude and 90° phase difference. It is mainly used for multi-signal combining to improve the utilization of output signals. It is widely used to combine base station signals in indoor coverage systems. The typical hybrid coupler is 3dB Hybrid Coupler, also known as 90-degree hybrid coupler, also called Quadrature Hybrid Couplers.
