CIRCULATORS

Pasquali Microwave Systems has the capability to design and manufacture waveguide 3 ports and 4 ports circulators from WR284 to WR28 standards with excellent performance for VSWR, Isolation and Insertion Loss.
Non-standard designs are available as well as high power devices development. Non standard designs include customised coaxial right-angled ports or end launchers depending on the customer’s requirements.

This new model of WR90 circulator has a very large operating frequency band, about 2000 MHz in the X band, with 20dB Isolation in the whole band and VSWR below 1.2 for all ports. Insertion Loss is below 0.3 dB. It can support an Average Power of 200 Watt and a Peak Power of 15 KWatt. It is also available in the Isolator version, where one of the ports is terminated with a high power waveguide load.

This waveguide circulator operates over a 600 MHz frequency band in the X-band. The electrical parameters are: VSWR below 1.1, Isolation above 30 dB, Insertion Loss below 0.2 dB.

This four-port WR90 circulator operates in a band of 9000 MHz across the X-band. VSWR is below 1.15 at all ports. The value of Insertion Loss is 0.25 dB for the single junction and 0.5 dB of the double junction. Single isolation is 20 dB, Double Isolation is 40 dB.

This circulator has excellent performance over a frequency range of 1000 MHz in the X band. It has three different standards on the ports: SMA coaxial, TNC coaxial, half-height WR90. Other configurations are possible depending on the specific requirements.
