TNC Reverse-Polarity Plug (Male) to SMA Reverse-Polarity Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD‑T5A75A/H44‑H4 is a high‑frequency RF adapter designed for reliable interconnection between a TNC reverse‑polarity plug (male) and an SMA reverse‑polarity jack (female). Engineered for 50‑ohm RF and microwave systems, this adapter supports broadband operation from DC to 18 GHz, making it suitable for demanding high‑frequency signal transmission applications. With a maximum VSWR of 1.30 and a corresponding return loss of ≥ 17.69 dB, the adapter ensures stable impedance matching and reduced signal reflection across the operating bandwidth. Low insertion loss performance, specified at ≤ 0.1 × √F (GHz) dB, helps preserve signal integrity in RF test, measurement, and communication systems. Both the TNC R/P and SMA R/P interfaces feature secure screw‑lock coupling mechanisms to maintain consistent electrical contact under vibration and mechanical stress.
Designed for durability and long‑term electrical stability, the ROSNOL AD‑T5A75A/H44‑H4 utilizes precision‑selected materials and controlled manufacturing processes. The center contacts are manufactured from phosphor bronze, with the TNC R/P side finished with 3 microinch gold plating over a non‑magnetic nickel‑phosphorus underplating to minimize contact resistance and ensure reliable high‑frequency performance. The connector bodies and coupling nut are precision‑machined from brass copper‑tin‑zinc alloy, providing excellent mechanical strength, corrosion resistance, and effective RF shielding. PTFE dielectric insulators are used on both interfaces to maintain stable electrical characteristics over an extended operating temperature range from ‑65°C to +165°C. The adapter supports a minimum of 500 mating cycles on each side and is rated for power handling up to 80 W at 2 GHz, making it suitable for high‑power RF adapter applications.
