Application-driven customization, simulation, evaluation and production transition.
We specialize in monolithic microwave integrated circuits (MMICs) for satellite applications, offering GaAs- and GaN-based ICs covering frequencies up to 31 GHz. Our portfolio includes high-performance RF switches, low-noise amplifiers (LNAs), power amplifiers (PAs), antenna-in-package (AiP) solutions, beamforming IC arrays, up- and downconverters, and control modules.
These technologies are widely used in satellite communications, enabling next-generation 6G non-terrestrial networks (NTN) to deliver high-speed, low-latency, and highly reliable connectivity.
We specialize in developing high-breakdown-voltage GaN on SiC power devices that deliver high efficiency, low power loss, and excellent thermal management. These devices are ideally suited for AC/DC and DC/DC converters, EV charging stations, onboard chargers, high-power fast-charging systems, and AI server power supplies — delivering exceptional performance in energy conversion and high-power applications.
We possess core expertise in epitaxial structure design and device layout optimization, supported by rigorous quality control and rapid mass-production capabilities to meet the demands of fast-growing global markets. With high efficiency and high linearity at the heart of our brand, Ultraband Technologies continues to advance RF and power technologies, unlocking limitless possibilities for a better world.
ABOUT ULTRABAND
Founded in 2020, Ultraband Technologies is a fabless semiconductor design company headquartered in Hsinchu, Taiwan. We develop RF, millimeter-wave and power semiconductor technologies for satellite communications, 5G mmWave, 6G NTN, IoT, energy and aerospace applications.
In the 1990s, when compound semiconductors were still considered a niche field, a group of pioneers in Taiwan boldly chose to follow a path few had taken.
Through unwavering commitment and long-term dedication, they overcame formidable challenges in materials, manufacturing processes, and market development. Their efforts ultimately gave rise to the globally renowned WIN Semiconductors and secured Taiwan a vital position in the global compound semiconductor industry.
Today, the founding team of Ultraband Technologies carries forward the same original vision and pioneering spirit. Once again standing at the forefront of an industry transformation, we are advancing third-generation semiconductor technologies and high-frequency integrated circuit design.
This is more than a continuation of technological expertise and pioneering spirit—it is a renewed journey to open new frontiers for next-generation communications and energy applications.
