RF Waveguide Termination, WR-90, UBR-100, 20 W, 8.20-12.5 GHz (X Band)

DLW90-U100-20 is a WR-90 RF waveguide termination for X Band applications, covering 8.20 to 12.5 GHz with an average input power rating of 20 W at 25 °C.

This waveguide termination is used as a load in microwave assemblies and RF subsystems where an unused port or line section must be properly terminated to reduce reflections and support stable system operation. The datasheet specifies a maximum VSWR of 1.2.

System role

The DLW90-U100-20 is suitable for terminating unused WR-90 waveguide ports and end sections in X Band microwave systems. It can be integrated into test benches, waveguide assemblies and RF subsystems that require a reliable matched load for rectangular waveguide interfaces.

Application context

This model is appropriate for laboratory setups, microwave signal routing chains and technical integration work where a standard WR-90 termination with square cover flange and moderate continuous power handling is required.

Mechanical information

The body is made of aluminum with a grey painted finish. The technical drawing in the datasheet provides the main flange and body dimensions needed for mounting checks and mechanical integration.
