General Description

The HMC894LP5E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 6%. The 20 dB filter bandwidth is approximately 16.5%. The center frequency can be varied between 5.9 and 11.2 GHz by applying an analog tune voltage between 0 and 14V. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC894LP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
