HMC895LP4ETR

Overview

The HMC895LP4ETR is a monolithic microwave integrated circuit (MMIC) bandpass filter manufactured by Analog Devices Inc. It features a user-selectable passband frequency tunable between 6.8 GHz and 12.6 GHz via an analog control voltage ranging from 0 V to 14 V. The device provides approximately 10% bandwidth at the 3 dB level and 22% at the 20 dB level. Key electrical specifications include a typical insertion loss of 9 dB, return loss of 12 dB, and input IP3 of 28 dBm. It operates within a temperature range of -40 °C to +85 °C and utilizes a 24-lead QFN package.

Feature Summary

• Monolithic design offering fast tuning response and excellent microphonics resistance
• Tunable low side and high side rejection notch capabilities for interference mitigation
• Single chip replacement solution for mechanically tuned filter banks

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance and lot traceability upon receipt. Ensure handling precautions are observed as the device is electrostatic sensitive with an ESD sensitivity rating of 150V HBM. Validate that the ordering suffix corresponds to the reel packaging format required for automated assembly processes.

Selection Notes

Select this component when dynamic frequency agility is required in the 6.8 to 12.6 GHz range. Ensure the control driver can supply the necessary source/sink current of ±1 mA for both center frequency and notch voltages. Verify that the system power budget accommodates the maximum operating voltage of 14 V and that thermal management supports the specified junction temperature limits under continuous operation.

Part Context

The HMC895LP4E belongs to the HMC895 series of tunable MMIC filters. This family is designed to replace physically large switched filter banks and cavity-tuned filters. The LP4E designation indicates a leaded plastic QFN package variant. The product line has been discontinued by Analog Devices following the acquisition of Hittite Microwave Corporation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the HMC895LP4E is marked obsolete, alternative solutions require manual evaluation of compatible tunable filter architectures.
