HMC980-SX

Overview

The HMC980-SX is an active bias controller manufactured by Analog Devices Inc., designed for high-current applications. It functions as a PMIC die intended for surface mount installation. The device operates within a supply voltage range of 4V to 12V and draws a supply current of 7.5mA. It supports an operating temperature range from -55°C to 85°C. The component is classified under dedicated power management ICs for current biasing purposes.

Feature Summary

• Automatically adjusts the gate voltage of external amplifiers to maintain constant bias current
• Designed for high-current active bias control applications
• Implemented as a bare die for custom substrate integration

Applications

• Current biasing for RF and microwave amplifier stages
• Gate voltage regulation for external transistor amplifiers
• High-current bias control in RF signal chain modules

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received die matches the specified package type and marking codes. Ensure handling procedures comply with electrostatic discharge (ESD) protection standards required for bare die components. Check for any specific storage conditions related to moisture sensitivity level classification before assembly.

Selection Notes

Select this component when precise, automatic adjustment of external amplifier gate voltage is required to sustain constant bias current. Consider its suitability for high-current applications and compatibility with the target operating temperature range. Evaluate the need for bare die integration versus packaged alternatives based on system design constraints and thermal management requirements.
