Circulator Microwave 101

The above diagram is the setup.

Circulator microwave 101.

A circulator is a device that transports radio frequency or microwave signals from one port to another. And of course the nmr unit and the power and cooling unit for the static b field. The 3 port circulator is formed by a 120 degree h plane waveguide and the 4 port circulator. They can be packaged as planar microstrip components coaxial components or as waveguide components.

4 port differential phase shift ferrite has a broad range of four port differential circulators. 3 port circulator s matrix and 4 port circulator s matrix. These devices are important for keeping signals flowing in one direction only. Posts about circulator written by goluckyryan.

Figure 1 shows the schemat ics for a circulator and an isolator. The upper one is laser unit the 2 devices between sample chamber and cro is field sweep unit. You can specify insertion loss down to less than 0 2 db in some cases. Depending on power and output mismatch conditions cooling can be performed either by air natural convection or forced or liquid.

The selection of basic ferrite material and magnet material has a significant effect on the overall performance and cost of circulators and isolators. Nova microwave designs and manufactures a comprehensive line of circulators for commercial applications military applications wireless and cellular markets. Uiy technology co ltd china supplier of rf isolator rf circulator microwave circulator microvave isolator filter.

Nova microwave staff has a thorough understanding of the working of ferrite and magnet materials and their application to develop electronic microwave circulators and isolators. Waveguide circulators and isolators have by far the best electrical characteristics. Circulators are available in frequencies ranging from 900mhz to 45ghz and in all standard industry bandwidths. And the lower part is the microwave unit.

The rotary field is very strong and will cause any rf microwave signals in the frequency band of interest at one port to follow the magnetic flow to the adjacent port and not in the opposite direction. Notice how an isolator is a circulator with the third port terminated.
