HMC877LC3

Overview

The HMC877LC3 is a broadband time delay and phase shifter manufactured by Analog Devices Inc. It features a continuously adjustable shift range of 0 to 500 degrees, equivalent to 1.4 UI. The device operates within a frequency range of 8 GHz to 23 GHz. Key electrical parameters include a propagation delay of 140 ps. Power supply requirements specify a minimum voltage of 3.135 V and a maximum of 3.465 V. The component is housed in an SMT-16 package and supports surface mount installation. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Provides continuously adjustable phase shift and time delay functionality across a wide bandwidth.
• Features linearly monotonic delay control for precise signal timing adjustments.
• Designed as a high-performance microwave monolithic integrated circuit (MMIC) for RF applications.

Applications

• Radar systems requiring precise beam steering or timing alignment
• Electronic warfare and electronic countermeasure systems
• High-frequency communication infrastructure

Procurement Notes

Verify current availability status carefully, as the HMC877LC3 is listed as End-of-Life and scheduled for obsolescence by the manufacturer. Confirm that existing stock or last-time-buy options meet project timelines. Ensure compatibility with the EVAL01-HMC877LC3 evaluation board if development testing is required before final integration into production designs.

Selection Notes

Select this component for applications requiring broad bandwidth phase adjustment between 8 GHz and 23 GHz. Consider the SMT-16 package constraints and the specific power supply voltage window of 3.135 V to 3.465 V. Evaluate the need for linearly monotonic delay characteristics in your signal processing chain. Account for the operational temperature range of -40°C to +85°C during thermal design.

Part Context

The HMC877LC3 belongs to the HMC877 series of microwave components. It is produced by Analog Devices Inc., which acquired Hittite Microwave Corporation, where the product was originally developed. This MMIC is categorized under delay lines and timing elements, serving specialized roles in high-frequency signal manipulation where traditional discrete solutions may lack performance or size efficiency.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Due to the End-of-Life status, direct replacements should be evaluated based on functional equivalence in radar and communication systems rather than pin-to-pin compatibility.
