HMC881LP5E

HMC881LP5E v01.0110 Typical Applications Features The HMC881LP5E is ideal for: Fast Tuning Response; 150 ns • Test & Measurement Equipment Excellent Wideband Rejection; 40 dB • Military RADAR & EW/ECM Single Positive Frequency Control: 0 to +14V • SATCOM & Space Low Insertion Loss & User Selectable Cutoff Frequency • Industrial & Medical Equipment TE Single Chip Replacement for Mechanically Tuned Designs 32 Lead 5x5 mm SMT Package General Description Functional Diagram LE The HMC881LP5E is a MMIC low pass filter which features a user selectable cutoff frequency. The cutoff frequency can be varied from 2.2 to 4.0 GHz by applying a single analog tuning voltage between 0 and 14V. This low pass filter provides a low 3.8 dB insertion loss, 10 dB return loss and 1.25 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 HMC881LP5E 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.
