Description
SMA Plug (Male) to SMA Jack (Female) | Adjustable Phase Shifter
The ROSNOL APS-A1A25A-18G15/9XX-9X SMA Adjustable Phase Shifter is engineered for precision phase control in high-frequency RF and microwave systems operating from DC to 18 GHz. Designed with a 50-ohm impedance, this phase shifter provides a controlled phase adjustment range of 15° × frequency (GHz) while maintaining excellent signal integrity, with a typical VSWR of ≤ 1.25. Low insertion loss performance, specified as ≤ 0.1 × √F (GHz) dB, ensures minimal signal degradation during phase tuning. The screw-lock coupling mechanism allows secure mating and stable performance under vibration, supporting applications that require repeatable and accurate phase alignment.
This adjustable phase shifter features a stainless steel body with passivated surface treatment for enhanced durability and corrosion resistance. The center contact is manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating, ensuring stable electrical contact and reliable long-term performance. PTFE dielectric insulation supports consistent electrical characteristics across a wide operating temperature range. The integrated phase adjustment nut and lock nut design allows fine tuning and secure locking of the desired phase setting, enabling precise control during system calibration and testing. With a mating life rated for 500 cycles, the APS-A1A25A-18G15/9XX-9X is well suited for laboratory, production, and field measurement environments.
ROSNOL adjustable phase shifters are precision-manufactured as cost-effective alternatives to leading RF component brands in North America and Europe. All ROSNOL RF components are produced in ISO 9001-certified facilities and comply with RoHS and REACH requirements. Customization services for phase range, materials, and mechanical configuration are available to support specialized RF and microwave design requirements.
