Part details & applications

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.

Applications

Testing and measurement equipment
Military radar and electronic warfare/electronic counter measure (ECM)
Satellite communication and space
Industrial and medical equipment
