HMC6787ALC5A

Overview

The HMC6787ALC5A is a compact GaAs MMIC I/Q variable gain upconverter designed for the 37 GHz to 40 GHz RF frequency range. It operates with a local oscillator (LO) frequency of 16.5 GHz to 22 GHz and an intermediate frequency (IF) range of 0 Hz to 4 GHz. The device provides a typical small signal gain of 10 dB, a P1dB compression point of 14 dBm, and an OIP3 of 26 dBm. It functions on a single 3 V supply, drawing currents of 150 mA and 200 mA. Power dissipation is rated at 1.65 W. The component is housed in a leadless RoHS-compliant SMT QFN-16 package.

Feature Summary

• Integrates I/Q modulation capabilities within a monolithic microwave integrated circuit structure.
• Utilizes Gallium Arsenide (GaAs) technology for high-frequency performance.
• Features variable gain control functionality for signal amplitude adjustment.
• Designed as a compact solution for millimeter-wave applications.

Applications

• Point-to-point wireless communication systems
• Satellite communication terminals
• Millimeter-wave radar subsystems

Procurement Notes

Verify the specific suffix LC5A against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through current datasheets. Check for moisture sensitivity level requirements during storage and handling. Ensure the supplier provides valid traceability documents. Validate that the component matches the exact part number before integration into design files.

Selection Notes

Select this component when designing upconversion stages requiring operation between 37 GHz and 40 GHz. Consider the 16.5 GHz to 22 GHz LO input range for frequency planning. Evaluate the 10 dB gain and 14 dBm output power against system link budget requirements. Assess the QFN-16 package constraints for PCB layout and thermal management. Verify compatibility with the 0 Hz to 4 GHz IF interface bandwidth.
