GENERAL DESCRIPTION

The ADMV8420 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

20%, and the 20 dB filter bandwidth is approximately 40%.

11.1 GHz to 19.6 GHz by applying a center frequency control

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

filter is a smaller alternative to switched filter banks and cavity

tuned filters. The ADMV8420 has minimal microphonics due

to the monolithic design and provides a dynamically adjustable

solution in advanced communications applications.
