FERRITE CIRCULATOR SWITCHES AND THEIR APPLICATIONS

摘要

When looking for a coaxial microwave switch that can handle moderate power levels, the options considered are likely to be a PIN diode switch or an electromechanical switch. Both of these switch types have been well engineered over the years, but still suffer from inherent disadvantages. The PIN diode switch introduces significant levels of distortion products, while the electromechanical switch is relatively slow, and has lower life expectancy and reliability. In contrast, coaxial circulator switches, which have not received much attention, are capable of significant improvement over the PIN diode and electromechanical switches in distortion products and mechanical reliability, respectively.
