Overview
The HMC941ALP4E 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 ideal for various high-frequency applications. The attenuator operates over a wide frequency range of 0.1 to 33.0 GHz, with an insertion loss of less than 4 dB typical. It features 0.5 dB least significant bit (LSB) steps, providing a total attenuation of 15.5 dB. The device is controlled by five voltage inputs, toggled between +5V and 0V, to select each attenuation state.
