HMC1068

Overview

The HMC1068 is a GaAs broadband distributed amplifier designed for high-speed optical modulation driver applications. It supports data rates up to 32Gbps and operates at frequencies up to 16 GHz. The device provides 15 dB gain with a power dissipation of 450 mW. It functions on a supply voltage ranging from 3.3 V to 7 V. Packaged as a bare die, it features adjustable output signal amplitude and crosspoint via control pins. An integrated peak detector ensures proper operation during normal use.

Feature Summary

• Optimized for time-domain performance in high-bandwidth applications
• Adjustable output signal amplitude and crosspoint through dedicated control pins
• Integrated peak detector functionality for operational monitoring

Applications

• Optical modulator driver circuits
• High-speed serial data transmission systems
• VSAT communication equipment

Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to discontinuation status. Confirm die-level handling requirements and electrostatic discharge protection protocols. Ensure compatibility with existing thermal management solutions given the 450 mW power dissipation specification. Validate that the bare die package format aligns with current board design constraints and assembly capabilities.

Selection Notes

Select this component when designing systems requiring high bandwidth up to 32Gbps with precise amplitude control. Consider the bare die form factor for custom packaging needs. Evaluate the need for external control circuitry to manage the adjustable crosspoint and amplitude features effectively within the system architecture.
