Low PIM Directional couplers are used in a wide variety of applications and can satisfy almost any requirement for sampling incident and reflected microwave power conveniently and accurately with minimal disturbance to the transmission line. Some general applications for directional couplers include line monitoring, power measurements and load source isolators. Low Passive-Intermodulation (PIM) couplers are ideal for LTE applications which ensures high data throughput. 

A directional coupler separates signals based on the direction of signal propagation. These devices are used to unequally split the signal flowing in the mainline and to fully pass the signal flowing in the opposite direction.

Each directional coupler is hand tested for optimal VSWR before shipping so performance is guaranteed.
