Filter - Tunable, Low Pass SMT, 4.5 - 7.6 GHz

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.
