HMC891LP5E Filter - Tunable, Band Pass SMT, 2 - 3.9 GHz
The HMC891LP5E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 9%. The 20 dB filter bandwidth is approximately 27%. The center frequency can be varied between 2 and 3.9 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 HMC891LP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
