Designed for the evolving 5G and automated testing landscape, these high-precision programmable attenuators handle the broad spectrum required for mid-band cellular deployment, providing a dynamic solution for signal level control in high-speed network environments. Unlike fixed components, these units are used at the critical interface of automated test equipment (ATE) and R&D validation setups to ensure the cleanest possible signal environment by allowing real-time adjustments to power levels without physical intervention. Key features include a wide frequency range supporting DC to 18 GHz (with mmWave options up to 40 GHz), fast switching speeds in the microsecond range, and highly accurate step resolutions from 0.1 dB to 1 dB. Engineered for carrier-grade performance, they feature a low VSWR of ≤ 1.4:1 and an ultra-low PIM design to maintain peak data throughput during complex handover and fading simulation tests. Built with robust mechanical interfaces such as SMA or N-Type connectors and integrated digital control ports (USB, Ethernet, or GPIB), these rugged programmable attenuators provide a secure, low-loss solution for permanent 5G lab installations, satellite link simulations, and high-capacity base station characterization.
