Description
Rotary Variable Attenuator | 0-11 dB | 0.1 dB Step | SMA Jack (Female) to SMA Jack (Female) | 2W | DC- 2.5 GHz | VSWR 1.4
The ROSNOL VA-A2A25A-2.5G2W0-11 rotary variable attenuator is designed for precise RF signal adjustment in laboratory, communication, and test applications. Featuring SMA female to SMA female interfaces and a 50-ohm impedance design, this attenuator provides smooth and repeatable attenuation control from 0 to 11 dB with fine 0.1 dB resolution. Its compact configuration supports accurate signal management across DC to 2.5 GHz frequency ranges.
Electrical performance includes VSWR ≤ 1.4, insertion loss ≤ 1.0 dB, and average power handling up to 2 W at 25°C. The high-resolution attenuation adjustment and specified attenuation accuracy help maintain stable signal conditioning during testing and calibration procedures.
Featuring a durable screw-on coupling mechanism, more than 500 mating cycles, and an operating temperature range of -40°C to +70°C, the ROSNOL VA-A2A25A-2.5G2W0-11 is well suited for RF measurement systems, wireless development, instrumentation, and signal optimization applications.
