HBT (Heterojunction Bipolar Transistor)

An HBT, or Heterojunction Bipolar Transistor, is an electronic device used to amplify signals in high-speed circuits. It consists of layers of different semiconductor materials, creating a junction that improves the flow of electrons. This structure enables faster operation and higher efficiency compared to traditional transistors. HBTs are commonly used in applications like wireless communication and radar because they can handle high frequencies and provide reliable amplification. Essentially, they are advanced transistors that leverage material differences to achieve better performance in electronic systems.
