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
center frequency (fCENTER). Additionally, fCENTER can be varied
between 16.5 GHz to 29.5 GHz by applying an analog tuning
voltage between 0 V to 15 V. This 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.
