RF transistor

ST's RF transistors are manufactured using an optimized process layout designed to improve RF performance. They exhibit outstanding RF gain and power saturation, higher breakdown voltage, improved ruggedness and reliability (higher MTTF). These unique features result in high-performance and cost-effective solutions.

With more than 35 years’ experience, ST offers a broad portfolio of Radio Frequency power transistors operating from 7 to 100 V. They are a perfect fit for applications ranging from 1 MHz to 4 GHz, such as:

  • Industrial, Scientific and Medical (ISM)
  • FM and TV Broadcast
  • Mobile and wideband communications
  • Avionics and Radar
  • Telecom and Satellite Communications

Several package options are available, from SMD plastic to ceramic and ST’s innovative STAC® air cavity package featuring 25% lower thermal resistance, improved RF performance and best-in-class reliability.

In addition to a wide range of evaluation boards and reference designs, ST offers software simulators and analysis tools to help engineers quickly get their designs to market.
