HMC881LP5E

Overview

The HMC881LP5E is a tunable low-pass surface-mount filter designed for frequencies between 2.2 GHz and 4.0 GHz. It features a single positive frequency control voltage ranging from 0 V to +14 V, allowing user-selectable cutoff frequencies within the specified range. The device offers fast tuning response of 150 ns and excellent wideband rejection exceeding 40 dB. Packaged in a RoHS-compliant 32-lead 5x5 mm QFN leadless package, it serves as a single-chip replacement for mechanically tuned designs.

Feature Summary

• Fast tuning response with a 150 ns switching time
• Excellent wideband rejection capability exceeding 40 dB
• Single positive frequency control voltage operation from 0 V to +14 V
• Low insertion loss with user-selectable cutoff frequency

Applications

• Test & Measurement Equipment
• Military RADAR & EW/ECM
• SATCOM & Space
• Industrial & Medical Equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm that the part matches the specific obsolete status indicated in official documentation. Ensure handling precautions are followed due to electrostatic sensitivity. Validate that the package marking and lot number correspond to the verified manufacturing records before integration into production systems.

Selection Notes

Select this component when replacing mechanically tuned filters with a compact monolithic solution. Ensure the application requires a cutoff frequency tunable between 2.2 GHz and 4.0 GHz. Verify that the system can provide a stable DC control voltage between 0 V and +14 V. Consider the 5x5 mm QFN package dimensions for PCB layout constraints and thermal management requirements.

Part Context

This component belongs to the Hittite Microwave Corporation product line, now integrated into Analog Devices. It is classified under tunable low-pass SMT filters. The datasheet indicates an obsolete status, suggesting it may be superseded by newer generations or discontinued from active manufacturing lines while remaining available for legacy support.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided datasheet. Consult Analog Devices technical support for current equivalent models or next-generation replacements suitable for the 2.2–4.0 GHz tunable low-pass filter category.
