Mini-Circuits launches wideband digital step attenuator from 0.1 to 24 GHz. Mini-Circuits has introduced the ZX76-24G-30-S+, a 50 ohm coaxial solid-state digital step attenuator designed for wideband RF applications spanning 0.1 to 24 GHz. Engineered for precision and flexibility, the attenuator offers programmable attenuation from 0 to 31.5 dB in 0.5 dB steps, providing fine control over signal levels across a wide frequency range. The ZX76-24G-30-S+ features a 6-bit parallel control interface that requires no external clock and supports dual (+3.3 V / -3.0 V) or single-supply operation (+3.3 V to +5.4 V). Built for durability in demanding environments, it delivers high input IP3 performance of +50 dBm, good return loss (typical 15 dB), and glitch-free attenuation transitions, making it well-suited for test instrumentation, communication infrastructure, and defense applications such as radar, EW, ECM, and SATCOM systems. The device's robust design also ensures immunity to latch-up and stable operation from 0°C to +50°C, while supporting input power levels up to +22 dBm. It operates with an insertion loss as low as 3 dB (typically) up to 13 GHz and 4.5 dB (typically) up to 24 GHz. To simplify integration, Mini-Circuits includes a CBL-5FT-MPD+ pigtail control cable, featuring stripped wire ends and a pre-mounted connector for easy interface with the attenuator's 10-pin digital control port. Compact and rugged, the ZX76-24G-30-S+ combines precision, programmability, and wide frequency coverage, enabling engineers to achieve reliable signal conditioning in both laboratory and field setups.

RF Design collaborated with Mini-Circuits' development teams on the project, holding frequent design reviews and both teams benefitted from Menlo's excellent applications engineering support team to facilitate the integration.
