Figure 1. GENERAL DESCRIPTION The ADMV8420 is a monolithic microwave integrated circuit voltage between 0 V to 15 V. The usable pass band corner (MMIC), tunable band-pass filter that features a user-selectable frequencies (fCORNER) span from 10 GHz to 21.7 GHz. This tunable pass band frequency. The 3 dB filter bandwidth is approximately filter is a smaller alternative to switched filter banks and cavity 20%, and the 20 dB filter bandwidth is approximately 40%. tuned filters. The ADMV8420 has minimal microphonics due Additionally, the center frequency (f ) varies between to the monolithic design and provides a dynamically adjustable CENTER 11.1 GHz to 19.6 GHz by applying a center frequency control solution in advanced communications applications.
