HMC520LC4

RF Mixers Overview

The HMC520LC4 is a GaAs MMIC I/Q mixer designed for surface-mount applications in the 6 GHz to 10 GHz frequency range. It features a leadless Pb-free SMT package, specifically a QFN-24 configuration. The device supports operation as either an Image Reject Mixer (IRM) or a Single Sideband upconverter. Key electrical specifications include a maximum conversion loss of 10 dB and a power dissipation rating of 340 mW. The component operates within a temperature range of -55°C to +85°C.

RF Mixers Feature Summary

• Integrates two standard double-balanced mixer cells with a 90-degree phase shift network on a single die
• Supports dual functionality as both an Image Reject Mixer and a Single Sideband upconverter
• Utilizes a compact leadless Pb-free surface-mount package for efficient PCB layout

RF Mixers Applications

• VSAT communication systems
• Point-to-point microwave links
• Satellite ground station equipment

RF Mixers Procurement Notes

Verify current availability status as the HMC520LC4 may be subject to discontinuation notices from Analog Devices. Confirm that the specific package variant matches design requirements. Check for moisture sensitivity levels and handling precautions due to the leadless SMT construction. Ensure compatibility with existing RF signal chain components before finalizing procurement plans.

RF Mixers Selection Notes

Select this component for applications requiring high linearity and low noise in the 6-10 GHz band. Consider the QFN-24 footprint for space-constrained designs. Evaluate thermal management capabilities given the 340 mW power dissipation limit. Compare against newer generations if long-term supply assurance is critical for the product lifecycle.

RF Mixers Part Context

This part belongs to the HMC520 series of I/Q mixers from Analog Devices. It shares architectural similarities with variants like the HMC520ALC4 but differs in packaging and specific operational parameters. The series is widely recognized for its performance in satellite communications and wireless infrastructure applications requiring precise phase and amplitude balance.
