Description
SMA Plug (Male) to SMA Jack (Female) | Adjustable Phase Shifter
The ROSNOL APS-A1A25A-18G23/9XX-9X SMA Adjustable Phase Shifter provides extended phase tuning capability for broadband RF and microwave applications from DC to 18 GHz. Designed with a controlled 50-ohm impedance, this model offers an increased phase adjustment range of 23° × frequency (GHz), enabling precise electrical length compensation and signal phase alignment. Excellent RF performance is maintained with a typical VSWR of ≤ 1.25 and low insertion loss characteristics, making it suitable for high-frequency measurement, calibration, and signal conditioning systems.
The phase shifter features a stainless steel body with passivated finish for enhanced environmental durability. Gold-plated beryllium copper center contacts with non-magnetic underplating ensure reliable electrical contact and long-term performance stability. A PTFE dielectric supports consistent RF behavior across temperature variations. The screw-lock coupling mechanism, combined with dedicated phase adjustment and locking nuts, allows accurate and repeatable phase tuning while preventing unintentional movement. With a mechanical endurance rating of at least 500 mating cycles, this model supports both laboratory and field use.
ROSNOL adjustable phase shifters are manufactured to meet the performance expectations of demanding RF system designers while offering a cost-efficient alternative to premium interconnect brands. All ROSNOL RF components comply with RoHS and REACH directives and are produced in ISO 9001-certified facilities. Design customization options are available to support specialized RF and microwave applications.
