Three 10dB Couplers Compared: Insertion Loss and PIM Test Results – Cavity vs Microstrip vs Stripline
Sep , 29 2026
In DAS indoor distribution systems and RF link designs, the 10dB directional coupler is one of the most frequently used passive components. The two specifications engineers care about most are insertion loss and passive intermodulation (PIM) — the former directly eats into the link budget, the latter determines whether the uplink noise floor can be kept down. There are three main manufacturing tec...
