HMC891LP5E v00.1209 FILTER - TUNABLE, BAND PASS SMT 2.0 - 3.9 GHz 3 FILTERS - TUNABLE - SMT Typical Applications The HMC891LP5E is ideal for: • Test & Measurement Equipment • Military, RADAR & EW • SATCOM & Space • R&D Laboratories Features Fast Tuning Response Excellent Wideband Rejection Single Chip Replacement for Mechanically Tuned Designs 32 Lead 5x5 mm SMT Package: 25 mm2 Functional Diagram General Description 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.
