15.1 GHz to 32 GHz, Tunable Band-Pass Filter

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 16.6 GHz to 30.1 GHz by applying an analog tuning voltage between 0 V to 15 V. The usable pass band corner frequencies (fCORNER) span from 15.1 GHz to 32 GHz. 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.
