Product Introduction

Overview

The HMC939 is a broadband 5-bit GaAs IC digital attenuator MMIC chip produced by Analog Devices Inc. This component operates across a wide frequency range of 0.1 to 40 GHz, making it highly versatile for various high-frequency applications. The attenuator features 1.0 dB least significant bit (LSB) steps, allowing for a total attenuation range of 31 dB. It is designed with a single positive control line per bit, ensuring easy and precise control over the attenuation states.
