    Waveguide Magic Tee

    A magic tee is a 4 ports microwave device which can be seen as a hybrid or 3 dB coupler. It can be used to isolate an emitter and a receiver using a single antenna and in RADAR or SATCOM applications. It can also be used as a power divider/combiner. Magic tees can be daisy-chained in order to achieve 4,8 or 16 ways power dividers / combiners. Because it is a waveguide device it can deal with very high power while keeping the insertion losses very low compared to a planar solution (such as microstrip or stripline). Giving the cost and the volume of such devices, they are often designed for specific applications so please contact us for any needs on such products.

    What is a Magic Tee?

    A Magic Tee is a 4 ports waveguide microwave device. It can be used as a 180 ° power combiner / divider or as a hybrid coupler. It has nearly the same properties as a planar rat-race coupler. It has been developed during WWII and published in 1947 by W.A. Tyrel.

    How does Magic tee as a power divider works?

    A signal coming to the port sum splits into two in-phase signals to the ports 2/3. A signal coming from port delta splits into two signals to the ports 2/3 but with a 180° phase shift.

    How does Magic tee as a power combiner works?

    If the input signals are in phase then the combined power is transferred to port sum. Usually the port delta is loaded with a 50 Ohm load in order to absorb any power/phase unbalance between the inputs.

    Magic Tee power combiners and dividers are isolated; therefore a very small amount of the power coming from port 2 is transferred to port 3 (and vice versa).

    If there is a 180° phase shift between the input signals, the principle is the same but the combined signal is transferred to port delta and the port sum is loaded

    What are the advantages of a Magic tee?

    Because it is waveguide component, power handling is not really an issue for this kind of product. It also offers very low insertion losses.

    What Magic Tee power divider / combiner are used for?

    Magic Tee waveguides are quite bulky and expensive so it is only use in specific applications such as RADAR or SATCOM where planar solutions are not able to keep up with the amount of power.
