Overview
The HMC425ALP3E is a broadband 6-bit GaAs IC digital attenuator produced by Analog Devices Inc. This component is designed in a low-cost leadless surface mount package, making it ideal for various high-frequency applications. It operates over a frequency range of 2.2 GHz to 8.0 GHz and features a single +3 to +5V supply voltage. The attenuator provides 0.5 dB least significant bit (LSB) steps up to a total attenuation of 31.5 dB, with an excellent attenuation accuracy of ±0.5 dB typical step error.
