RF Transistors are semiconductor devices designed to amplify, switch, or control electrical signals at radio frequencies. As a core category within Wireless & RF Semiconductors, they support the handling of high-frequency signal paths where stable gain, low noise behavior, and predictable impedance characteristics are important.

These devices are commonly implemented using different transistor technologies and material systems to address varying RF performance needs. RF transistors are typically provided as discrete components and are selected based on their suitability for operation in RF signal chains.

• Primary role: RF signal amplification and switching
• Signal domain: Radio-frequency and related high-frequency ranges
• Common device families: Bipolar transistors and field-effect transistors
