Understanding MMICs and Their Applications

Millimeter-wave integrated circuits are critical for a wide array of applications, including 5G communications, satellite communications, automotive radar, and security systems. Operating within the frequency range of 30 GHz to 300 GHz, these circuits facilitate high data rates, superior resolution, and enhanced system performance. The intrinsic properties of GaAs and GaN—such as high electron mobility, thermal conductivity, and breakdown voltage—make them ideal materials for MMIC fabrication.

GaAs MMICs have traditionally been favored for their excellent low-noise performance and high-frequency capabilities, making them suitable for applications like satellite communications.
