HMC313

Overview

The HMC313 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) monolithic microwave integrated circuit (MMIC) amplifier designed for surface-mount applications. It operates from a single 5 V supply with a typical current consumption of 50 mA. The device provides a gain of 17 dB across a frequency range of DC to 6 GHz. Key performance metrics include a noise figure of 6.5 dB, a P1dB compression point of 14 dBm, and an output third-order intercept point (OIP3) of 27 dBm. It is housed in a compact SOT-23-6 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes high-reliability GaAs InGaP HBT process technology for robust MMIC performance.
• Operates efficiently from a single voltage supply, simplifying power management requirements.
• Offers broadband amplification capabilities suitable for wideband gain stages or narrowband optimized designs.

Applications

• Broadband gain stages in RF signal chains
• WLAN system implementations
• Narrowband application optimization with external matching

Procurement Notes

Verify component status carefully as the HMC313 is officially listed as End-of-Life (EOL). Confirm availability through authorized distributors or check for specific discontinuation notifications from Analog Devices. Ensure that any replacement strategies account for the cessation of production and potential supply chain constraints associated with obsolete components.

Selection Notes

Select this component when a low-noise, moderate-gain amplifier is required for frequencies up to 6 GHz. Consider its single-supply operation and SOT-23-6 footprint for space-constrained designs. Evaluate the trade-off between its 17 dB gain and 6.5 dB noise figure against system sensitivity requirements. Verify thermal dissipation limits given the 259 mW power dissipation specification.

Part Context

The HMC313 belongs to the HMC313G series of RF amplifiers manufactured by Analog Devices Inc. It is categorized under Wireless & RF Integrated Circuits. As a gain block amplifier, it serves as a fundamental building block for radio frequency front-end modules, providing essential signal conditioning and amplification in wireless communication architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the EOL status. Consult Analog Devices official resources for recommended obsolescence alternatives.
