Infineon PIN diodes are ideal for a wide range of RF applications. Their low insertion loss and fast switching time makes them ideal for use in Rx-Tx antenna switches. They are offered in industry-standard 0201 and 0402 form factors as well as conventional industry packages and various junction diode configurations.
28 gru 2016 · This article will introduce the challenge of RF switching and describe the basics of PIN diode operation. It will then show how to design with PIN diodes, before providing some real-world PIN diode examples to show how the technology is advancing.
RF switches based on FET and PIN diodes are essential for controlling signals in RF circuits. These switches operate on distinct principles, offering low loss and high isolation. In this guide, we discuss FET and PIN diode RF switch circuits, their working and provide diagrams to aid understanding.
All PIN diode switch models offer leading edge performance with low insertion loss. These RF switches have extremely high isolation levels with ultra-fast switching speeds. Pasternack RF PIN diode switches are available in compact coaxial packages, most with field replaceable SMA connectors.
PIN diodes, which sandwich a lightly doped intrinsic (I) region between heavily doped P and N regions, are used extensively in RF and microwave applications. Common applications of PIN diodes are microwave switches, phase shifters, and attenuators, where high isolation and low loss are required.
Typically, the PIN diode is used in RF through microwave fre- quency modulators and switches. Since the diode is in shunt with the RF path, the RF signal is attenuated when the diode is forward biased (“ON”), and is passed unattenuated when the diode is reversed biased (“OFF”).
Infineon Pin Diodes come with low loss and low distortion levels and are suitable for a wide range of mobile communications and RF applications. This series of diodes can operate up to 6GHz with high-voltage handling capabilities and together with outstanding RF performance, they simplify design-in because of their extreme low forward ...
