Description

An SMA female–female–female (FFF) adaptor is a T-shaped coaxial connector with three SMA female ports, used to split or combine RF signals in systems where SMA male connectors are standard. Here's a technical overview: - Configuration: SMA jack (female) on all three ports - Impedance: 50 Ohms - Frequency Range: DC to 18 GHz (varies by manufacturer) - VSWR: Typically ≤1.25:1 up to 6 GHz - Construction: - Body: Brass or stainless steel with nickel or gold plating - Center Contacts: Gold-plated beryllium copper - Insulator: PTFE (Teflon) - Applications: RF signal branching, antenna testing, lab instrumentation, and microwave circuits
