Description
SMA Plug (Male) to SMA Jack (Female) | Adjustable Phase Shifter
The ROSNOL APS-A1A25A-18G15/944-94 SMA Adjustable Phase Shifter is designed to deliver stable and repeatable phase control for RF systems operating up to 18 GHz. This model offers a nominal 50-ohm impedance and a phase adjustment range of 15° × frequency (GHz), supporting accurate signal tuning across broadband measurement and communication platforms. With a typical VSWR of ≤ 1.25 and optimized insertion loss characteristics, the phase shifter maintains consistent signal quality throughout the adjustment range. The screw-lock coupling design provides reliable mechanical retention and consistent electrical contact during repeated adjustments.
Constructed using high-quality brass components with copper-tin-zinc alloy plating, the body and coupling hardware provide dependable mechanical strength and conductivity. The beryllium copper center contact is gold plated with a nickel underlayer to support low contact resistance and stable RF performance. A PTFE insulator ensures dielectric stability under varying environmental conditions. The integrated phase adjustment and locking nut structure allows smooth phase tuning while securely maintaining the selected position. This makes the APS-A1A25A-18G15/944-94 suitable for RF test fixtures, system calibration, and prototype validation environments.
ROSNOL adjustable phase shifters deliver consistent performance and mechanical reliability as competitive alternatives to established RF component suppliers. Manufactured under ISO 9001-certified quality systems, ROSNOL products are fully compliant with RoHS and REACH regulations. Custom configurations are available to meet specific frequency, material, and mechanical design requirements.
