There are three main types of Waveguide Tees:
1. E-Plane Waveguide Tee
2. H-Plane Waveguide Tee
3. E-H Plane Waveguide Tee(Magic Tee, or Hybrid or 3dB coupler)
Dolph Microwave provides a series of high-performance waveguide tees, power divider, and combiner products. By connecting a load to the E and H plane tee, it can be made into a Magic T power divider or synthesizer. The magic tee in microwave engineering has the characteristics of opposite port isolation, adjacent 3 dB coupling and perfect matching, which makes wave guide tees widely used in the microwave field, especially used in monopulse radar and difference comparator, radar transceiver switch, power distribution/combination, mixed Frequency converter and phase shifter.
Flange type: Multiple types of waveguide tee in microwave available - see Dolph Microwave Flanges page.
Finish: Corrosion protection plus black top coat of our waveguide magic tee in microwave engineering.

Magic T waveguide are widely used as hybrid circuits in microwave impedance bridges, balanced mixers in receivers, and frequency
discriminators.
The structure is composed of an E-plane branch and H-plane branch coupled with each other, providing good impedance characteristics and
symmetric property over the entire frequency range.
E-plane and H-plane waveguide has been designed to minimize the leakage of RF wave between the E-plane and H-plane branches with other waveguide ports perfectly matched.
Double-ridged magic T waveguide can provide more bandwidth than "normal" rectangular waveguide Magic T.
1. Measure the impedance
A null detector is connected to E-Arm port while the Microwave source is connected to H-Arm port. The collinear ports together with these ports make a bridge and the impedance measurement is done by balancing the bridge.
2. As a duplexer
The duplexer is a circuit which works as both the transmitter and the receiver, using a single antenna for both the purposes. Port 1 and 2 are used as receiver and transmitter where they are isolated and hence will not interfere. An antenna is connected to E-Arm port. A matched load is connected to H-Arm port, which provides no reflections. Now there exists transmission or reception without any problem.
3. As Microwave Bridge, Microwave discriminator, etc.

There are three main types of Waveguide Tees:
1. E-Plane Waveguide Tee
2. H-Plane Waveguide Tee
3. E-H Plane Waveguide Tee(Magic Tee, or Hybrid or 3dB coupler)
When the axis of the side arm is parallel to the Electric Field (E) of the collinear, then the tee is called a E-Plane Tee Junction.
When the axis of the side arm of the waveguide tee is parallel to the flow of the Magnetic Field (H) from port 1 and is perpendicular to the flow of the Electric Field (E), then the tee is called a H-Plane Waveguide Tee.
An E-H Plane Tee junction is formed by attaching two simple waveguides one parallel and the other series, to a rectangular waveguide which already has two ports. This is also called as Magic Tee, or Hybrid or 3dB coupler.
The outputs we get in this type of tee are 180° out of phase with each other, irrespective of from which port the input is fed.
If the input signal is fed to port 3, then the output will be split across port 1 and 2 and will be 180 degrees out of phase with each other.
An H-Plane Waveguide Tees can be thought of as a two way in-phase power divider/combiner i.e it is additive in nature. When two input signals are fed to port 1 & 2, the output at port 3 is in phase and additive and when the input signal is fed to port 3, the signal is split in to two equal parts that are in-phase at port 1 & 2.
The arms of rectangular waveguides make two ports called collinear ports i.e., Port 1 and Port 2, while the Port 3 is called as H-Arm or Sum port or Parallel port. Port 4 is called as E-Arm or Difference port or Series port.
A Magic Plane Tee is a 4 ports waveguide microwave device. The magic T waveguide can be used as a 180 ° power combiner / divider or as a hybrid coupler.
