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:	1.30
	E - Arm:	1.30
	E - Arm:	1.50
	• Isolation:
	H & E Arms:	30dB
	Co-linear Arms:	16dB

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, mechanically assembled as shown.
General Description: ● Models above are configured as shown using standard W/G and flanges ● All Tees are aluminum ● NO INTERNAL TUNING or matching. E plane to H plane Isolation is a function of the symmetry which is carefully balanced on each unit. For a true Magic Hybrid Tee see ATM’s 830 type.
