MICROSEMI CORP

Microsemi Corp, a specialty player nestled within the Semiconductors & Related Devices SIC environment, focuses on developing high-reliability analog and mixed-signal components such as power management chips, timing and synchronization devices, and RF subsystems tailored for aerospace, defense, and industrial communications customers seeking rugged performance and long lifecycle support; the firm also services niche commercial telecom and data center needs where signal integrity and energy efficiency are mission-critical. With manufacturing and quality systems aligned to regulated defense procurement standards and supply-chain scrutiny, Microsemi navigates material risks tied to defense spending cycles, export controls, component obsolescence, and compliance with DoD cybersecurity mandates, all while monitoring evolving semiconductor trade policies that shape access to key global suppliers.
