HMC897LP4ETR

Overview

The HMC897LP4ETR is a monolithic microwave integrated circuit (MMIC) bandpass filter manufactured by Analog Devices Inc. It features a user-selectable passband frequency tunable between 9 GHz and 19 GHz via an analog control voltage ranging from 0 V to 14 V. The device exhibits a typical 3 dB bandwidth of approximately 18% and a 20 dB bandwidth of roughly 35%. Key electrical specifications include a maximum insertion loss of 6.5 dB, a return loss of 9.5 dB, and an input IP3 of 30 dBm. It operates within a temperature range of -40°C to +85°C and is housed in a 24-lead 4x4 mm surface-mount package.

Feature Summary

• Provides a dynamically adjustable solution for advanced communications applications through analog tuning.
• Offers excellent microphonics performance due to its monolithic design.
• Serves as a compact single-chip replacement for physically large switched filter banks and cavity-tuned filters.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'TR' against official documentation to confirm reel packaging requirements. Confirm current availability status as discontinuance notices may affect supply chain continuity. Ensure compatibility with existing RF ground plane designs and thermal management strategies during integration.

Selection Notes

Select this component when a wide tuning range from 9 GHz to 19 GHz is required in a small form factor. Consider the 6.5 dB insertion loss and 30 dBm IP3 for system link budget calculations. Ensure the control driver circuit can provide the necessary ±1 mA source/sink current and low noise for optimal phase noise performance.

Part Context

The HMC897LP4ETR belongs to the HMC897 series of tunable bandpass filters from Analog Devices. This series is designed to replace mechanically tuned solutions in RF front-ends. The part integrates filtering capabilities into a single MMIC, reducing board space and complexity compared to traditional discrete filter assemblies.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other Hittite/Analog Devices tunable filter models or consult manufacturer application support for direct replacements.
