HMC519LC4TR

Overview

The HMC519LC4TR is a low noise surface-mount amplifier from Analog Devices Inc., designed for VSAT applications. It operates within the 18 GHz to 31 GHz frequency range and utilizes Silicon technology. The device is housed in a 24-lead TFCQFN package with exposed pad, measuring 4x4 mm. Key electrical specifications include a typical gain of 14.4 dB, a noise figure of 3.5 dB, and a P1dB compression point of 12.2 dBm. It requires a 3 V supply voltage and draws a supply current of 75 mA.

Feature Summary

• Optimized for Very Small Aperture Terminal (VSAT) systems
• Low noise figure performance for signal integrity
• High linearity with defined P1dB characteristics
• Surface-mount LGA/CQFN packaging for compact integration

Applications

• VSAT communication uplink/downlink chains
• Point-to-point microwave radio links
• Satellite communication ground stations
• Ka-band radar systems

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel quantity and handling specifications. Confirm moisture sensitivity level (MSL) ratings prior to PCB assembly to ensure proper reflow soldering profiles. Check for RoHS compliance status as indicated in the latest datasheet revision. Ensure ESD precautions are observed during storage and handling due to the sensitive RF nature of the component.

Selection Notes

Select this component when designing Ka-band front-ends requiring minimal signal degradation. Compare the 3.5 dB noise figure against system link budget requirements. Evaluate the 14.4 dB gain to determine if additional amplification stages are necessary. Consider the 24-CQFN footprint for PCB layout constraints and thermal management needs relative to the 75 mA power consumption.

Part Context

This part belongs to the HMC519G series of low noise amplifiers. It is functionally similar to the HMC519LC4TR-R5 variant, which shares identical core RF performance but may differ in reel packaging specifications. Other family members like the HMC517LC4TR cover adjacent lower frequency bands (17-26 GHz).

Replacement Considerations

The HMC519LC4TR-R5 is a direct functional equivalent within the same series. Verify that the -R5 suffix does not alter the reel quantity or shipping configuration if strict inventory continuity is required.
