SMA 50 Ohm Jack (Female) to F 75 Ohm Plug (Male) Matching Pad, DC-2GHz VSWR 1.25

Impedance Matching Pad, 50Ω SMA Jack (Female) to 75Ω F Plug (Male)

The ROSNOL MP-A25F17A-2G/H4-H44 impedance matching pad enables a 50 Ω (SMA) to 75 Ω (F) transition from DC to 2 GHz with VSWR ≤ 1.25 (≥ 19.08 dB) and nominal attenuation 5.7 ± 0.5 dB. It is rated 0.7 W at 40 °C with linear derating to 0 W at 125 °C. Mechanical data: SMA and F screw‑lock coupling, ≥ 500 mating cycles per side, recommended torques 0.57 Nm (SMA) / 1.1 Nm (F), and coupling test torques up to 1.70 Nm (SMA) / 6.78 Nm (F). Operating temperature −40 °C to +85 °C. (Model: MP-A25F17A-2G/H4-H44)

Piece-part materials and plating: SMA side—centre contact: phosphor bronze, gold plated with non‑magnetic Ni‑P underplate; body: brass, copper‑tin‑zinc alloy; insulator: PTFE. F side—centre contact: phosphor bronze, gold plated with non‑magnetic Ni‑P underplate; body: brass, copper‑tin‑zinc alloy; insulator: PTFE; coupling nut: brass, copper‑tin‑zinc alloy. This pad supports interconnection between 50 Ω RF instruments and analyzers and 75 Ω CATV/IF/coax distribution networks across test & measurement labs, broadcast/CATV systems, and telecom/broadband installations where consistent 50↔75 Ω matching is required.
