What is a waveguide isolator?
A waveguide isolator is a two port device. They transmit microwave or RF power in one direction only. It is basically a modified circulator. Isolators have one port terminated with a matched impedance. Typically, they are used for preventing high power transmitter outputs from interfering with sensitive devices, receiver circuitry, and power sources.
The main purpose and function of a waveguide isolator is to:
- Act as a one way valve for microwave or RF energy
- Protect RF or microwave power sources from reflected power
- Direct all reflections away from the power source, often into a load
How They Work: A Visualization
See the diagram below for a visual represenation of how waveguide isolators typically operate.
Designing, Engineering, and Manufacturing Waveguide Isolators
Similar to other passive RF devices, when exploring a potential design for a waveguide isolator, the following technical specifications, electrical and mechanical data, as well as environmental requirements should be considered:
- Isolation
- Frequency
- Bandwidth
- Insertion loss
- Pressurization
- Flange type and size
- Forward power (peak/average)
- Reflected power (peak/average)
- Special environmental requirements
- Cooling system (temperature, connectors, etc.)
There are several other factors that may come into play when discerning waveguide isolators for your application. For the best fit device, provide the product specialists at Microwave Techniques with as much information as possible.
