Microwave Techniques - Waveguide FXR Loads

Waveguide FXR Loads

Microwave Techniques manufactures waveguide FXR loads in several different sizes, power levels and configurations for microwave and RF applications.

FXR Loads by Microwave Techniques is a product line that consists of unfinned (WE series), finned (WF series), super high power (WG series), and liquid cooled (WL series) waveguide loads.

Each series provides different objectives. FXR Loads are available in sizes ranging from WR28 to WR650. This covers a frequency range from 1.12 to 40 GHz.

If you do not see the specific waveguide FXR load you require, contact sales@microwavetech.com to discuss your exact product requirements with a technical sales engineer.

Please note all product data, specifications, and descriptions are subject to change at the sole discretion of Microwave Techniques and must be confirmed at the time of order.

¹ 30,000 V/cm Breakdown Voltage Unpressurized Waveguide 1:00:1 VSWR Average power is based upon unpressurized painted aluminum waveguide, internal surface finish of 63µm, under free convective cooling with an operating temperature that is 25oC above ambient temperature. Cooling options should be considered if the waveguide will be operating at higher average power levels - please consult factory.
