Overview
The HMC891ALP5E is a monolithic microwave integrated circuit (MMIC) band-pass filter designed by Analog Devices Inc. This component features a user-selectable pass band frequency, making it a versatile solution for various advanced communications applications. The filter can be tuned to operate within a frequency range of 1.95 GHz to 3.4 GHz by applying an analog tune voltage between 0 V and 14 V. This tunability allows it to replace larger, mechanically tuned designs and cavity tuned filters, offering a more compact and dynamically adjustable solution.
