HMC896LP4E

Overview

The HMC896LP4E is a monolithic microwave integrated circuit (MMIC) bandpass filter operating in the 10 to 18 GHz range. It features user-selectable passband frequency controlled by an analog voltage between 0 and 14V applied to the center frequency control pin. The device exhibits a typical 3 dB bandwidth of approximately 9% and a 20 dB bandwidth of 22%. Key electrical specifications include a maximum insertion loss of 9 dB, return loss of 11 dB within the 2 dB bandwidth, and an input IP3 of 26 dBm at input powers from 0 to +15 dBm. The component utilizes a 24-lead QFN package measuring 4x4 mm.

Feature Summary

• Fast tuning response with phase settling to within 10 degrees in less than 200 nanoseconds
• Excellent wideband rejection capabilities with tunable low side and high side rejection notches
• Single chip replacement for mechanically tuned designs, offering a dynamically adjustable solution
• Monolithic design providing excellent microphonics immunity

Applications

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

Procurement Notes

Verify component authenticity through authorized Analog Devices channels or certified distributors. Confirm RoHS compliance status and check for Product Change Notifications (PCN) prior to procurement. Ensure handling precautions are observed due to electrostatic sensitivity. Validate that the specific lot number matches current manufacturing standards. Review datasheet revisions for any updates to electrical characteristics or mechanical dimensions before finalizing orders.

Selection Notes

Select this component when a compact, electronically tunable bandpass filter is required for frequencies between 10 and 18 GHz. It serves as a direct replacement for bulky switched filter banks or cavity-tuned filters. Designers must provide stable analog control voltages between 0 and 14V for both center frequency and notch rejection. Ensure the application environment supports the specified operating temperature range of -40°C to +85°C and accommodates the thermal dissipation requirements of the QFN-24 package.

Part Context

The HMC896LP4E belongs to the Hittite Microwave Corporation product line, now part of Analog Devices Inc. It is categorized under Tunable Filters within the RF and Microwave Integrated Circuits portfolio. This MMIC represents a transition from discrete mechanical tuning solutions to solid-state electronic control, enabling smaller form factors in advanced communication systems. The device is marked with 'H896' followed by a four-digit lot number on the package surface.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the datasheet indicates the product is obsolete, engineers should consult Analog Devices for current equivalent products or alternative MMIC tunable filters that meet the 10-18 GHz specification and 24-lead QFN footprint requirements.
