Description
Rotary Variable Attenuator | 0-70 dB | 1 dB Step | SMA Jack (Female) to SMA Jack (Female) | 10W | DC- 2.5 GHz | VSWR 1.4
The ROSNOL VA-A2A25A-2.5G10W0-70 rotary variable attenuator is engineered for precise RF signal level control in communication, laboratory, and test environments. Featuring SMA jack (female) to SMA jack (female) interfaces and a 50-ohm impedance design, this attenuator provides adjustable attenuation from 0 to 70 dB with 1 dB step resolution. Operating across DC to 2.5 GHz, it supports accurate signal conditioning and measurement applications where flexible attenuation control is required.
Designed for dependable RF performance, the attenuator offers VSWR ≤ 1.4, insertion loss ≤ 1.0 dB, and average power handling up to 10 W at 25°C. The specified attenuation accuracy across the full adjustment range helps ensure stable and repeatable results during testing, calibration, and system optimization.
The ROSNOL VA-A2A25A-2.5G10W0-70 features a durable screw-on coupling mechanism, supports more than 500 mating cycles, and operates from -40°C to +70°C. Its combination of high power handling, wide attenuation range, and robust construction makes it ideal for RF laboratories, wireless infrastructure, microwave systems, and signal management applications.
