Description
SMA Plug (Male) Adjustable Phase Trimmer | Soldered Cable Entry | Screw-lock | Stainless Steel Body
The ROSNOL SMA1E50‑PS141A/9XX is an adjustable RF phase trimmer featuring an integrated SMA plug (male) interface, designed for precision phase tuning in 50 Ω RF and microwave systems. Operating over a wide frequency range from DC to 18 GHz, this component provides an adjustable phase response of approximately 3.5 degrees per GHz, enabling fine phase alignment and signal optimization directly within cable assemblies and RF networks. Unlike standard cable connectors, this model incorporates an internal phase adjustment structure, making it suitable for applications requiring precise electrical length compensation and phase matching. A screw‑lock coupling mechanism ensures secure mating, while the soldered cable entry supports stable electrical continuity with semi‑rigid and conformable .141 cable types.The main body and coupling nut are manufactured from stainless steel with a passivated finish, delivering excellent mechanical strength, corrosion resistance, and dimensional stability. The center contact is made from beryllium copper with gold plating over a non‑magnetic nickel‑phosphorus underplating to ensure reliable conductivity, minimal contact resistance, and stable RF performance during adjustment. A PTFE insulator and silicone rubber gasket are used to maintain consistent dielectric characteristics and mechanical integrity throughout the operating frequency range. The SMA1E50‑PS141A/9XX is compatible with ROSNOL RSF‑141, RSR‑141, EF402, UT‑141, RG402/U, RTK‑FS 141, RTK‑Flex 402, and BELDEN 1673A cable types.
ROSNOL’s precision‑engineered RF components provide a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF products are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH requirements, ensuring environmental safety and global regulatory alignment. Customization services for mechanical structure, materials, and electrical characteristics are available to support specialized RF phase control and interconnect requirements.
