HMC813LC4BTR

Overview

The HMC813LC4B is a Successive Detection Log Video Amplifier (SDLVA) with limited RF output, operating from 1 to 20 GHz. It provides a logging range of 55 dB and operates from a single +3.3 V supply, consuming 153 mA. The device features typical fast rise/fall times of 5/10 ns and a log video output slope of 15 mV/dB. Maximum recovery times are less than 15 ns. It is housed in a compact 4x4 mm SMT ceramic package.

Feature Summary

• Successive detection architecture for high-speed channelized receiver applications
• Limited RF output capability alongside log video signal generation
• Single positive supply operation simplifying power requirements
• High frequency flatness ensuring consistent performance across the band

Applications

• EW, ELINT & IFM Receivers
• DF Radar Systems
• ECM Systems
• Broadband Test & Measurement
• Power Measurement & Control Circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required packaging or testing standards. Confirm that the component meets all necessary environmental and safety certifications for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring wideband logarithmic detection up to 20 GHz. Ensure the application can accommodate the single +3.3 V supply requirement and the specified 153 mA current consumption. Verify that the 4x4 mm ceramic package dimensions fit within the available PCB real estate constraints.

Part Context

This part belongs to the Hittite Microwave Corporation product line, which was acquired by Analog Devices Inc. It serves as a specialized analog front-end solution for microwave and millimeter-wave applications, bridging the gap between raw RF signals and processed video outputs for immediate amplitude analysis.

Replacement Considerations

Consult official Analog Devices documentation for verified substitute part numbers. Do not assume functional equivalence with other SDLVA models without cross-referencing pinouts and electrical specifications.
