It was also used in a number of microwave applications, although it took until around 1960 before its use became more popular in this application. Join our social networks below and stay updated with latest contests, videos, internships and jobs! b) Single pole double throw switch © All Rights Reserved. The term PIN diode gets its name from the fact that includes three main layers. (Look at the chart above, and notice that 50 ohms occurs very close to the center of the response). of Kansas Dept. An excellent primer on PIN diode circuit design is available on the Skyworks Solutions Inc. site. View Answer, 10. Nonlinear effects in such shunt PIN diode attenuators' are analysed, too. The high resistive layer of the intrinsic region provides the large electric field between the P and N-region. In the series configuration of a PIN diode switch, the terminated load impedance was found to be 50 Ω and the diode impedance was 60 Ω. The behavior of a PIN diode is entirely different from normal diodes at all frequency of operation. Participate in the Sanfoundry Certification contest to get free Certificate of Merit. Under ideal conditions, when a PIN diode is used as a switch, the switch must have _______ insertion loss in the ON state. View Answer, 9. Thanks for the correction, Morten! In this article we’ll show you how they work and why they’re so well suited for microwave applications. In this chapter, we shall discuss about the microwave components such as microwave transistors and different types of diodes. The number of PIN diodes used in SPST switch and SPDT switch are the same. c) GaAs If you can't find what you are looking for, please contact us. The Pin diode in reverse biased is used in various devices working at microwave frequencies such as microwave switch. A Schottky diode is an excellent example of a rectifier diode, that's why it is used as a detector. It is a 3-layer device in which an intrinsic layer i.e., undoped semiconductor is sandwiched between P and N regions.
