Description

15 dB Directional Coupler: A general listing for a 15 dB coupler; good starting place. N Direction Coupler (≈15 dB): Larger connector (likely coaxial N‑type) version; suitable if you use N‑Female connectors. 15.5 dB SMT Directional Coupler: Board‑mount version, lower power perhaps; good for PCB/test setups. 15.5 dB SMT Bi‑Directional Coupler: Bi‑directional board version, useful for measurement both forward and reverse. SMA Directional Coupler (≈15 dB): SMA connector version; likely smaller form factor. 16 dB Directional Coupler: Slightly higher coupling (16 dB) if you need a little more decoupling. And two backups/variants if you want to compare price/specs
