Low Frequency Zero Bias Detectors (WR-15 to WR-10)

 

These detectors have a rectangular waveguide RF input port and coaxial output. The drawings and corresponding dimensions are for a typical WR-10 and WR-15 
zero bias detector. The WR12ZBDs have similar form factor to the WR15ZBD. 

 

 
 
 
 
 
 
 
 
 
 

 
Middle Frequency Zero Bias Detectors (WR-8.0 to WR-1.0)

 

These detectors have a rectangular waveguide RF input port and coaxial output. The drawings and corresponding dimensions are for typical WR-3.4 zero bias 
detectors. Other ZBDs (WR-8.0 to WR-1.0) have similar configuration and dimensions. 

 

 
 
 
 
 
 
 
 
 
 
High Frequency Zero Bias Detectors (WR-0.8 to WR-0.65)

 

The WR0.8ZBD has an integrated horn antenna (~25dBi) RF input port and a coaxial output. The WR0.65ZBD has a rectangular waveguide RF input port and a 
coaxial output. The drawing and corresponding dimensions are for a typical WR-0.65 and WR-0.8 zero bias detector.
