HMC424LP3TR

Attenuators Overview

The HMC424LP3TR is a broadband 6-bit GaAs IC digital attenuator MMIC chip manufactured by Analog Devices Inc. It covers a frequency range from DC to 13 GHz with a typical insertion loss of less than 4 dB. The device features a 0.5 dB least significant bit (LSB) step size, providing attenuation values from 0.5 dB to 31.5 dB in 64 discrete steps. It operates on a single -5 V supply and utilizes a 3 mm LCC surface-mount package.
