GENERAL DESCRIPTION

The ADMV8432 is a monolithic microwave integrated circuit

(MMIC), tunable band-pass filter that features a user selectable

pass-band frequency. The 3 dB filter bandwidth is >17% of the

between 16.6 GHz to 30.1 GHz by applying an analog tuning

voltage between 0 V to 15 V. The usable pass band corner

tunable filter can be used as a much smaller alternative to

physically large switched filter banks and cavity tuned filters.

This tunable filter has excellent microphonics due to the

monolithic design and provides a dynamically adjustable

solution in advanced communications applications.
