Waveguide / Transforming waveguide
Generally, coaxial lines are commonly used for transmission lines below 3GHz, but waveguides are used for kW-level microwave power transmission in industrial applications. (The waveguide transmission line is referred to as a "three-dimensional circuit" in contrast to cables.) There are various standards for waveguides depending on the transmission frequency and purpose, but the ones we manufacture and sell are mainly the WRJ-2 standard waveguide and the WRT-2 standard waveguide (commonly known as Toshiba standard waveguides). We keep standard stock of straight tubes, E-corners, and H-corners (made of aluminum), and we also accommodate custom orders (such as wanting stainless steel material or specific dimensions). Coaxial waveguide converters are used when converting from waveguides to coaxial lines, and we offer two types: WRJ-2⇔WX-39D and WRJ-2⇔WX-20D. A vacuum window allows for the introduction of microwaves into a vacuum load (such as a vacuum chamber) by being inserted between the microwave three-dimensional circuit and the vacuum load. Additionally, it can be used to prevent the intrusion of gases (such as outgassing from the heated object or water vapor) into the waveguide.
