What Gallium Semiconductor does

Gallium Semiconductor was a Singapore-based, private fabless semiconductor company founded in 2020 that designed and manufactured radio-frequency (RF) power amplifiers and transistors based on Gallium Nitride (GaN) on Silicon Carbide (SiC) HEMT (High Electron Mobility Transistor) technology. The company operated with a headcount of 11-50 employees and ran the website galliumsemi.com. Its core product portfolio comprised over 65 GaN cores available in both bare die form and packaged variants — QFN (Quad Flat No-Lead), DFN (Dual Flat No-Lead), ACP (Air Cavity Plastic), and ACC (Air Cavity Ceramic). Named production devices included the GRF0005, delivering 5 Watt P3dB across DC to 12 GHz, and the GRF0012, delivering 12 Watt P3dB, both reaching full production status during the company's operational period.

The portfolio addressed six primary use-case verticals: 5G infrastructure, satellite communications (SatCom), military radar, electronic warfare, ISM-band industrial heating, and test & measurement. Pricing was not publicly disclosed, no customer logos or revenue figures were made available, and the company pursued a horizontal segmentation approach across these demanding RF applications.

On April 26, 2024, Guerrilla RF (GRF), a U.S.-based RF semiconductor company headquartered in Greensboro, North Carolina, completed the strategic acquisition of Gallium Semiconductor's complete GaN device portfolio, including all previously released devices and all cores under development. Under the transaction, GRF obtained the right to reassign GRF-specific part numbers to existing devices and is integrating the portfolio into its operations, ordering systems, direct sales channel, and applications support infrastructure. Following the acquisition, Gallium Semiconductor effectively ceased independent operations; customers were redirected to GRF sales for both pricing inquiries and technical support during the transition.
