700 to 2500MHz Coaxial Circulator

5o1032320 is a Coaxial Circulator is a passive, non-reciprocal ferromagnetic device used in Radio Frequency (RF) and microwave systems to control the direction of signal flow. It typically has three ports and functions as a “one-way street” for RF energy, forcing signals to circulate in only one designated direction.

The Fundamental Principle: Circulation

In a standard 3-port coaxial circulator, signal power can only flow from one port to the next in a predetermined circular path:

Power entering Port 1 exits at Port 2.

Power entering Port 2 exits at Port 3.

Power entering Port 3 exits at Port 1.

Product Features:

Broad frequency coverage from 700 to 2500MHz

High isolation up to 23dB minimum

Excellent VSWR as low as 1.20

Low insertion loss maximum 0.6dB

High power handling 100W forward/reverse

Multiple connector options (N-type, SMA)

Compact size 32×32×18mm

Wide operating temperature range (-40°C to +85°C)

Application Areas:

Cellular base station power amplifier protection

Satellite communication systems

Military and aerospace radio systems

Public safety communication networks

Broadcast transmission systems

RF test and measurement equipment

This behavior is known as non-reciprocity, meaning the path the signal takes depends on its direction of travel. This effect is achieved using a magnetized ferrite material at the core of the device, which interacts with the RF signals based on the Faraday Rotation effect.
