HMC882LP5E v01.0310 FILTER - TUNABLE, LOW PASS SMT 4.5 - 7.6 GHz Features Fast Tuning Response; 150 ns Excellent Wideband Rejection; 40 dB Single Positive Frequency Control: 0 to +14V Low Insertion Loss & User Selectable Cutoff Frequency Single Chip Replacement for Mechanically Tuned Designs 32 Lead 5x5 mm SMT Package 3 FILTERS - TUNABLE - SMT Typical Applications The HMC882LP5E is ideal for: • Test & Measurement Equipment • Military RADAR & EW/ECM • SATCOM & Space • Industrial & Medical Equipment Functional Diagram General Description The HMC882LP5E is a MMIC low pass filter which features a user selectable cutoff frequency. The cutoff frequency can be varied from 4.5 to 7.6 GHz by applying a single analog tuning voltage between 0 and 14V. This low pass filter provides a low 2.9 dB insertion loss, 10 dB return loss and 1.23 x ƒcutoff stopband attenuation of >20 dB. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. The HMC882LP5E has excellent microphonics due to the monolithic design, and provides a dynamically adjustable solution in advanced communications applications. The low pass tunable filter is packaged in a RoHS compliant 5x5mm QFN leadless package.
