Description
SMA Jack (Female) to SMA Jack (Female) Rotary Variable Attenuator | 0–71 dB | 2 W | DC–2.5 GHz
The ROSNOL VA-A2A25A-2.5G2W0-71/H4-H4 rotary variable attenuator enables wide-range signal attenuation from 0 to 71 dB with 0.1 dB step resolution, operating across DC to 2.5 GHz with 50 Ω impedance. Designed for stable and flexible RF signal control, it maintains VSWR ≤ 1.5 and consistent electrical performance across global RF environments.Featuring gold-plated phosphor bronze contacts and a copper-tin-zinc alloy plated brass housing, the unit ensures excellent conductivity and corrosion resistance. PTFE dielectric guarantees stable electrical characteristics, while the screw-on coupling provides secure connection and long-term durability with ≥500 mating cycles.
ROSNOL attenuators meet global compliance requirements including RoHS and REACH, offering reliable performance for international RF systems.
