Waveguide Tees    

General Description:

   ?   All tees are aluminum
   ?  These models are configured as shown using standard WG and flanges.

800 Series Tee:
ATM's 800 series tee is an E plane tee.The junction of the auxiliary arm is made on the broad wall of the main waveguide.

810 Shunt Tee:
ATM's shunt tee is an H plane tee.  The junction of the auxiliary arm is made on the narrow wall of the main waveguide.

820 Hybrid Tee:
ATM's 820 hybrid tee is a Low cost 4 port device with both E & H plane tee's,

Waveguide Magic Tees



General Information:

ATM's 830 Magic Hybrid tee is a 4 port device assembled as shown with INTERNAL TUNING Devices for matching, balance and isolation. E plane to H plane Isolation is a function of the symmetry which is carefully balanced on each unit. If the E plane port 4 or the H plane port 2 are used as inputs the split is on the output collinear ports 1 and 3. When the input is E plane port 4 the outputs are out of phase 180 deg. When the input is H plane port 2 the outputs are in phase.

 ? VSWR :

 

   H - Arm:

 ? Isolation:

 

   H & E Arms:
