ADMV8420ACPZThe 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%. Additionally, the center frequency (fCENTER) varies between 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 frequencies (fCORNER) span from 10 GHz to 21.7 GHz. This tunable 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.ADMV8420CHIPSThe ADMV8420 is a monolithic microwave IC (MMIC), tunable band-pass filter (BPF) 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%. Additionally, the center frequency (fCENTER) varies between 10.5 GHz to 21 GHz by applying a center frequency control voltage (VFCTL) between 0 V to 15 V. The usable pass band 3 dB corner frequency (f3dB) spans from 10 GHz to 22.8 GHz. This tunable filter is a smaller alternative to switched filter banks and cavity tuned filters.
