128531-HMC890LP5E

HMC890LP5E v01.0310 Typical Applications Features The HMC890LP5E is ideal for: Fast Tuning Response; 200 ns • Test & Measurement Equipment Excellent Wideband Rejection; 30 dB • Military RADAR & EW/ECM Single Chip Replacement for Mechanically Tuned Designs • SATCOM & Space • Industrial & Medical Equipment 32 Lead 5x5 mm SMT Package General Description TE Functional Diagram LE The HMC890LP5E is a MMIC band pass filter which features a user selectable passband frequency. The 3 dB filter bandwidth is approximately 11%. The 20 dB filter bandwidth is approximately 33%. The center frequency can be varied between 1 and 2 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 HMC890LP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications.
