Key Specifications
Description
Rotary Variable Attenuator | 0–71 dB | SMA Jack (Female) to SMA Jack (Female) | 2 W | DC– 2.5 GHz | VSWR 1.5
The ROSNOL VA-A2A25A-2.5G2W0-71 is a precision rotary variable attenuator developed for applications requiring wide-range RF signal control. Operating from DC to 2.5 GHz, this 50-ohm attenuator utilizes SMA female connectors and provides an extensive attenuation range from 0 to 71 dB with precise 0.1 dB adjustment steps. It is ideal for RF testing, communication networks, system calibration, and laboratory measurement environments.
Key electrical specifications include VSWR ≤ 1.5, insertion loss ≤ 1.5 dB, and average power handling of 2 W at 25°C. Its defined attenuation accuracy supports reliable signal level adjustment throughout the full attenuation range.
The ROSNOL VA-A2A25A-2.5G2W0-71 features a robust screw-on interface, supports more than 500 mating cycles, and operates across temperatures from -20°C to +85°C. These characteristics make it suitable for demanding RF and microwave applications requiring stable attenuation control.
