Inquiry Elements for Waveguide Circulator
The three main factors of circulator are "Insertion loss (forward loss)", "Isolation (reverse direction loss)" and VSWR.

Since the circulator has a frequency characteristic, the specific frequency range are also needed when you look for this components.

At last, the power handling are also necesary since the colling method needs to take into consideration if high power needed.

Application of circulator and isolator in microwave
A waveguide isolator is a modified circulator having one port terminated with a matched impedance. Both the devices are typically used for preventing high powered transmitter outputs interfering with sensitive receiver circuitry. It efficiently does so by separating received signals at the input of the antenna from the transmitter's signals. In another way you can understand isolator is a cirulator with a termination.

There are many waveguide suppliers, but we are one of the best choices for you.
