HMC577LC4B

Overview

The HMC577LC4B is a surface-mount GaAs MMIC frequency multiplier designed for DBS and VSAT applications. It operates as an x2 multiplier with an output frequency range of 27 GHz to 31 GHz. The device functions within a supply voltage window of 4.5 V to 5.5 V, drawing a typical operating current of 213 mA. It dissipates up to 1.24 W of power and is housed in a compact 24-lead QFN (4x4 mm) package. The component supports operation across a temperature range from -40°C to +85°C.

Feature Summary

• Integrated GaAs MMIC technology for high-frequency performance
• Doubles input frequency to generate 27–31 GHz output signals
• Optimized for satellite communication link architectures

Applications

• Direct Broadcast Satellite (DBS) systems
• Very Small Aperture Terminal (VSAT) networks
• Millimeter-wave signal generation circuits

Procurement Notes

Verify availability status carefully, as the component may be subject to limited supply or factory special order constraints. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the specific ordering suffix matches the required packaging format. Validate RoHS compliance documentation against current regulatory standards before finalizing procurement decisions.

Selection Notes

Select this component when a compact, high-output frequency multiplier is required for Ka-band satellite links. The integrated design reduces board space compared to discrete solutions. Verify that the input drive levels align with the multiplier's linear range. Consider the thermal management capabilities of the PCB layout due to the specified power dissipation characteristics.
