Description
SMA Jack (Female) to SMA Jack (Female) Rotary Variable Attenuator | 0–101 dB | 2 W | DC–2.5 GHz
The ROSNOL VA-A2A25A-2.5G2W0-101/H4-H4 rotary variable attenuator is engineered for extended attenuation range up to 101 dB with fine 0.1 dB step control. Operating from DC to 2.5 GHz with 50 Ω impedance, it ensures precise signal level adjustment with VSWR ≤ 1.5 and stable insertion characteristics, supporting high dynamic range RF measurements and global signal control systems.
Built with gold-plated phosphor bronze center contacts and copper-tin-zinc alloy plated brass body, it delivers reliable electrical performance and corrosion resistance. PTFE insulation ensures consistent dielectric properties, while the robust screw-on interface supports long service life with ≥500 mating cycles.
ROSNOL products are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, providing globally trusted RF attenuation solutions.
