In 2002, EM Design addressed the performance limitations of traditional 3-port junction circulators by developing (and patenting) a distributed, phase-shift 3-port circulator.
While many in the industry think ‘junction 3-port’ when they hear ‘distributed 3-port’ as an option for their project, it’s important to understand the differences between the two and the benefits of using a distributed 3-port in your system.
The distributed 3-port has some significant advantages:
- It is stable and has consistent operating performance.
- It has the ability to operate at higher peak and average powers. For example, at S-band, the distributed 3-port circulator operates up to 8 MW peak power and 30 KW average power.
- It is not water temperature sensitive.
- It can also act as a replacement for larger 4-ports. If your performance requirements can be met with this design, it eliminates a fourth port and the corresponding absorption load. It is also significantly smaller.
