Description

Does the frequency band cover all the carriers / services you’ll use (e.g., 698-2700, 3400-3800, etc)? What is the coupling accuracy / flatness across the band (±dB) — you want minimal variation. What is the insertion loss (on the through port) — the lower the better to maintain signal strength. What is the directivity & isolation — higher directivity means better separation of forward vs reverse, useful for monitoring or measurement. What is the VSWR / Return Loss — good matching reduces reflections. What is the power handling (average & perhaps peak) — if the line carries high power you need a suitable rating. What is the PIM rating (if multi-carrier, strong signals) — low PIM is a must in DAS/IBS.
