GENERAL DESCRIPTION
The ADMV8416 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 approximately 15% of the center frequency (fCENTER), and the 20 dB filter bandwidth is 37%.
Additionally, fCENTER can be varied between
7 GHz to 16 GHz, Tunable Band-Pass Filter ADMV8416

7 GHz to 16 GHz by applying an analog fCENTER tuning voltage between 0 V to 15 V.
This tunable filter can be used as a much smaller alternative to large switched filter banks and cavity tuned filters.
The filter has excellent microphonics due to the monolithic design and provides a dynamically adjustable solution.
