HMC895LP4E

HMC895LP4E v01.0911 FILTER - TUNABLE, BAND PASS SMT 6.8 - 12.6 GHz Features Fast Tuning Response Excellent Wideband Rejection Tunable low side/high side rejection “notch” Single Chip Replacement for Mechanically Tuned Designs 24 Lead 4x4 mm SMT Package 3 FILTERS - TUNABLE - SMT Typical Applications The HMC895LP4E is ideal for: • Test & Measurement Equipment • Military RADAR & EW/ECM • SATCOM & Space • Industrial & Medical Equipment Functional Diagram General Description The HMC895LP4E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 10%. The 20 dB filter bandwidth is approximately 22%. The center frequency can be varied between 6.8 and 12.6 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 HMC895LP4E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
