HMC881LP5E v01.0110 FILTER - TUNABLE, LOW PASS SMT 2.2 - 4.0 GHz 3 Typical Applications Features The HMC881LP5E is ideal for: Fast Tuning Response 150 ns Excellent Wideband Rejection 40 dB Test & Measurement Equipment Single Positive Frequency Control: 0 to +14V Military RADAR & EW/ECM 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 General Description Functional Diagram 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 cutoff stopband attenuation of >20 dB. This tunable filter can be used as a much smaller alternative to physi- cally large switched filter banks and cavity tuned fil- ters. The HMC881LP5E has excellent microphonics due to the monolithic design, and provides a dynami- cally 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.

Data measured with a high speed op-amp driver and includes driver slew rate delay. Information furnished by Analog Devices is believed to be accurate and reliable.
