GENERAL DESCRIPTION
The HMC891ALP5E is a monolithic microwave integrated
circuit (MMIC) band-pass filter that features a user-selectable
pass band frequency. The 3 dB filter bandwidth is approximately
9% and the 20 dB filter bandwidth is approximately 23%. The
center frequency (fCENTER) can be varied between 1.95 GHz and
3.4 GHz by applying an analog tune voltage between 0 V and 14 V.
This tunable filter can be used as a smaller alternative to
physically large switched filter banks and cavity tuned filters.
The HMC891ALP5E has excellent microphonics due to the
monolithic design, and provides a dynamically adjustable
solution in advanced communications applications.
