HMC898LP4E v00.0511 FILTERS - TUNABLE - SMT 3 FILTER - TUNABLE, BAND PASS SMT 11.5 - 21.5 GHz Typical Applications Features The HMC898LP4E is ideal for: Fast Tuning Response • Test & Measurement Equipment Excellent Wideband Rejection • Military RADAR & EW/ECM Single Chip Replacement for Mechanically Tuned Designs • SATCOM & Space • Industrial & Medical Equipment Functional Diagram 24 Lead 4x4 mm SMT Package General Description The HMC898LP4E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 17%. The 20 dB filter bandwidth is approximately 35%. The center frequency can be varied between 11.5 and 21.5 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 HMC898LP4E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
