Overview
The HMC424ALP3E is a broadband, 6-bit gallium arsenide (GaAs) digital attenuator produced by Analog Devices Inc. It is packaged in a low-cost, leadless surface-mount technology (SMT) package, specifically a 16-lead lead frame chip scale package (LFCSP). This attenuator covers a frequency range from DC to 13 GHz, making it suitable for a variety of high-frequency applications.
The device features 0.5 dB least significant bit (LSB) steps, allowing for a total attenuation range of 31.5 dB with a typical step error of ±0.5 dB. It operates with a single negative supply voltage ranging from -3 V to -5 V and requires an external level shifter for interfacing with CMOS or transistor-to-transistor logic (TTL) interfaces.
