HMC882LP5E v01.0310 FILTER - TUNABLE, LOW PASS SMT 4.5 - 7.6 GHz 3 Typical Applications Features The HMC882LP5E 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 Low Insertion Loss & SATCOM & Space User Selectable Cutoff Frequency Industrial & Medical Equipment Single Chip Replacement for Mechanically Tuned Designs 32 Lead 5x5 mm SMT Package 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 cutoff 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. Electrical Specifications, T = +25C A Parameter Min. Typ. Max.
