It is commonly used in modern ultrafast circuits, mostly radio frequency (RF) systems, and in applications requiring a high power efficiency, such as RF power amplifiers in cellular phones. The idea of employing a heterojunction is as old as the conventional BJT, dating back to a patent from 1951. [ 1 ]

Visual depiction of a compact wireless keyboard. A wireless keyboard is a computer keyboard that allows the user to communicate with computers, tablets, or laptops with the help of radio frequency (RF), such as WiFi and Bluetooth or with infrared (IR) technology.
"As a result, it is increasingly difficult to implement traditional pin-diode switch solutions. The PE42850/51 RF switches offer superior performance, with low power consumption, high linearity ...
MOSFET, showing gate (G), body (B), source (S), and drain (D) terminals. The gate is separated from the body by an insulating layer (pink).. The MOSFET (metal–oxide–semiconductor field-effect transistor) [1] is a type of insulated-gate field-effect transistor (IGFET) that is fabricated by the controlled oxidation of a semiconductor, typically silicon.
Fig. 1: The power devices family, showing the principal power switches. A power device may be classified as one of the following main categories (see figure 1): A two-terminal device (e.g., a diode), whose state is completely dependent on the external power circuit to which it is connected.
Mechanical keyboards (or mechanical-switch keyboards) are computer keyboards which have an individual switch for each key. The following table is a compilation list of mechanical keyboard models, brands, and series:
