Description

QuinStar’s QJH  Matched Hybrid Tees (magic tees) cover the frequency range of 18 – 170 GHz in nine waveguide bands. These four-port devices balance power-combining and dividing RF signals over a broad bandwidth. QJH has four ports: an H-plane port, an E-plane port, and two co-linear ports. A signal entering the H-plane port will be equal to the two co-linear ports, but not to the E-plane port. The output signals coupled to the two co-linear ports are in phase. Similarly, a signal applied to the E-plane port will divide equally into the two co-linear ports; however, the output signal will be 180 degrees out of phase with each other. If two signals of equal amplitude are applied to the co-linear ports, the signals will be coupled to the E-and H-plane ports.

The amount of power combined at the E- and H-plane ports depends on the relative phase relationship between the two input signals as follows:

PH / PE = [cos(phi/2)/ sin(phi/2)]2, where phi is the relative phase difference between the two input signals

Hence, if the two signals are in phase, the total power will be combined at H-plane port. If the two signals are 180 degrees out of phase, the total power will appear at E-plane port. The isolation between the co-linear ports is greater than 20 dB, and between the E-plane and H-plane ports is greater than 30 dB.

Applications

Typical applications for these Matched Hybrid Tees include power dividers/combiners, bridge circuits, balanced mixers, amplifiers, and instrumentation setups. QuinStar can provide custom 4- or 8-way power dividers by combining several hybrid tees (power dividers) into a single housing. We can also configure the hybrid junctions to achieve unequal power split in 3, 5, 6, or 7 ports.

Custom Configurations

QuinStar Technology can also supply custom configurations (“folded tees”) with output ports in different locations than in the standard product. Other power dividers (short slot hybrids and “rat-race” hybrids) are also available as special orders. If your application requires a unique power division scheme, please contact sales@quinstar.com with your requirements or submit an RFQ.
