Overview
The HMC468ALP3E is a broadband 3-bit GaAs IC digital attenuator produced by Analog Devices Inc. It is designed in a low-cost leadless surface mount package, making it suitable for a variety of high-frequency applications. The attenuator operates from DC to 6.0 GHz, with an insertion loss of less than 1 dB typical up to 4 GHz. It features 1 dB LSB steps, providing a total attenuation of 7 dB. The device is controlled by three single control lines per bit, each toggled between 0 and +5V, and requires a single +5V supply voltage.
