General Description
The HMC899LP4E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 18%. The 20 dB filter bandwidth is approximately 35%. The center frequency can be varied between 18.5 and 37.0 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 HMC899LP4E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
