Key Specifications
Description
Rotary Variable Attenuator | 0-101 dB | 0.1 dB Step | SMA Jack (Female) to SMA Jack (Female) | 2W | DC- 2.5 GHz | VSWR 1.5
The ROSNOL VA-A2A25A-2.5G2W0-101 rotary variable attenuator offers ultra-wide attenuation control for advanced RF and microwave applications. Designed with SMA female to SMA female connectors and 50-ohm impedance, this attenuator provides a broad attenuation range from 0 to 101 dB in precise 0.1 dB increments. It is an excellent solution for signal simulation, calibration, laboratory testing, and communication system development.
Performance specifications include DC to 2.5 GHz frequency coverage, VSWR ≤ 1.5, insertion loss ≤ 1.5 dB, and average power handling up to 2 W at 25°C. The detailed attenuation accuracy characteristics support consistent and repeatable signal conditioning across the full adjustment range.
Built with a screw-on coupling mechanism and rated for more than 500 mating cycles, the ROSNOL VA-A2A25A-2.5G2W0-101 operates from -20°C to +85°C. Its combination of broad attenuation range and fine step resolution makes it ideal for RF laboratories, testing systems, instrumentation, and precision microwave signal management.
