Description

Frequency band coverage: Does it cover the exact band(s) you need (e.g., 698-960, 1710-2700, 3400-3800 MHz)? Coupling tolerance / flatness: How much variation across the band (±dB)? Insertion/thru loss: The smaller the extra loss the better, especially if long coax runs. Directivity & isolation: Higher directivity means better separation of forward vs reflected signals; important if you use the coupler for monitoring/reflection measurement. Power handling: Both average and peak (if applicable). If it's for high-power DAS/IBS, ensure sufficient rating. Connectors & compatibility: Make sure connector types (N, 4.3-10, DIN, SMA) match your system, and that you have adapters if needed. Return loss / VSWR: Good matching means less reflection and better system performance. Impedance: Usually 50 Ω for telecom; ensure that’s the standard.
