HMC813LC4B

Overview

The HMC813LC4B is a Successive Detection Log Video Amplifier (SDLVA) manufactured by Analog Devices, formerly Hittite Microwave. It operates within a frequency range of 1 to 20 GHz and features limited RF output. The device utilizes a surface-mount LGA-24 package designed for high-frequency signal processing applications.

Feature Summary

• Implements successive detection log video amplifier architecture for wideband signal monitoring
• Provides limited RF output capability to protect downstream components
• Operates across a broad microwave frequency spectrum from 1 to 20 GHz

Applications

• Signal strength monitoring in communication systems
• Spectrum analysis equipment input stages
• Radar system signal detection

Procurement Notes

Verify the manufacturer designation as Analog Devices Inc., reflecting the acquisition of Hittite. Confirm the specific suffix LC4B corresponds to the LGA-24 package variant. Ensure compatibility with 50 Ohm system impedance requirements for the specified frequency range.

Selection Notes

Select this component when a wideband SDLVA solution is required for frequencies up to 20 GHz. The limited RF output feature distinguishes it from standard amplifiers, making it suitable for direct connection to detectors or power meters without external attenuation.

Part Context

This part belongs to the Hittite/Analog Devices portfolio of high-performance microwave integrated circuits. The HMC813 series specifically targets applications requiring logarithmic response over a wide dynamic range in the C, X, Ku, and K bands.
