Overview
The ADMV8432ACPZ from Analog Devices Inc. is a monolithic microwave integrated circuit (MMIC) that functions as a tunable band-pass filter. This device allows for user-selectable pass-band frequencies, making it a versatile component for various high-frequency applications. The center frequency (fCENTER) can be adjusted between 16.6 GHz and 30.1 GHz by applying an analog tuning voltage ranging from 0 V to 15 V. This tunable filter is designed to replace larger switched filter banks and cavity tuned filters, offering a compact and dynamically adjustable solution for advanced communications systems.
