OPTIMAL CONNECTIVITY offers Low PIM RF Couplers which are passive RF devices being able to couple a specific proportion of the power travelling in one transmission line out through another connection or port. 

Directional couplers have many applications in DAS systems, RF testing, line power sensors and transmitter power levels control. All our low PIM Couplers have a 50Ω impedance and are environment rated at IP66.

Low PIM RF Couplers do not reflect incoming RF signals as our Couplers have a low Insertion Loss (low IL) and therefore avoid increase of noise levels in RF networks.

For high quality SNR applications 50Ω low PIM RF Couplers are deployed throughout every DAS network, typically to feed different branches of a DAS infrastructure.

All PIM values of our Couplers are measured against IM3 (dBc@2*43dBm) and are lower than ≤-160dBc.
