The ZX76-44G-30-K+ from Mini Circuits is a Digital Step Attenuator that operates from 100 MHz to 43.5 GHz. It has an adjustable attenuation range from 0 to 31.5 dB in 0.5 dB steps with a switching time of less than 400 ns. This attenuator offers glitch-free attenuation transitions and hence, reduces noise in the system and eliminates the risk of a transient voltage spike that can damage sensitive components in a system. It can handle an input power of up to 28 dBm and has an insertion loss of less than 5.5 dB. This attenuator has a 6-bit parallel control interface with a wide control voltage range that eliminates the need for using clocks, thereby simplifying synchronization between components.
The ZX76-44G-30-K+ uses a single positive supply that simplifies the power supply design and results in excellent spurious performance. It has an internal negative voltage generator to supply the desired negative voltage and can also externally apply a negative voltage to support applications that require the lowest possible spurious performance. This RoHS-compliant attenuator is available in a module that measures 1.78 x 1.20 inches and has 2.92 mm-female connectors. It is ideal for EW test sets, general-purpose test setups, X-band, S-band, C-band, Ku-band, and K-band radars, satellite communication, and 5G applications.
