Overview
The HMC1018ALP4E is a broadband 5-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 wide range of high-frequency applications. The attenuator operates over a frequency range of 0.1 to 30.0 GHz, with an insertion loss of less than 5.5 dB typical. It features 1.0 dB least significant bit (LSB) steps, providing a total attenuation range of 31 dB. The device is controlled via a CMOS/TTL compatible serial interface, allowing for precise and flexible attenuation settings.
