HMC318MS8GTR

Overview

The HMC318MS8GTR is a surface-mount variable gain low noise amplifier (VGLNA) designed for C-band applications, covering the full UNII and HiperLAN frequency bands from 5 GHz to 6 GHz. It operates on a single 3 V supply with a typical current consumption of 6 mA. The device provides a gain of 9 dB and achieves a noise figure of 2.5 dB. Key performance metrics include a P1dB compression point of 2 dBm and an OIP3 of 13 dBm. It features an input return loss of 12 dB and dissipates 634 mW of power. The component is housed in an 8-MSOP package with an exposed pad.

Feature Summary

• Integrates automatic gain control functionality within a compact surface-mount package
• Optimized for low noise performance in wireless communication bands
• Utilizes GaAs technology for efficient operation at high frequencies

Applications

• HiperLAN receiver front-ends
• UNII band wireless local area network systems
• C-band signal processing circuits

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm availability status as distribution channels may indicate limited stock or obsolete status. Ensure compatibility with existing board layouts regarding the exposed pad thermal requirements and pinout configuration before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring integrated gain control and low noise amplification in the 5 to 6 GHz range. Consider the trade-off between the 9 dB gain and the 2.5 dB noise figure relative to system sensitivity requirements. Evaluate the 6 mA supply current against total power budget constraints for portable or battery-operated wireless devices.

Part Context

This part belongs to the HMC318 series of variable gain low noise amplifiers manufactured by Analog Devices. It is specifically engineered to serve both UNII and HiperLAN standards within the C-band spectrum. The MS8G variant denotes the surface-mount package style suitable for automated assembly processes in modern RF circuit manufacturing.

Replacement Considerations

Consult official Analog Devices substitution guides for compatible alternatives. Verify that any substitute maintains identical pinout, operating voltage, and frequency range specifications to ensure direct interchangeability without redesigning the surrounding RF circuitry.
