Definitions
- the invention relates to a microwave hybrid ring according to the preamble of claim 1.
- a microwave hybrid ring is known for example from JP-A-57-97 204.
- This ring hybrid is not a 180 ° - another 90 0- ring hybrid. It only serves as a phase switch for diodes. Power is fed in via a first connection arm and is led to diodes via two further connection arms which are closely adjacent to the first connection arm.
- the object of the invention is to provide a realization for a 180 ° or 90 ° ring hybrid, with all connecting arms being galvanically decoupled from one another and reflections being suppressed.
- the connecting arms of the ring hybrid are designated by the reference numerals 1, 2, 3 and 4. They are located on the top of the dielectric carrier substrate 5 and are designed as microstrip lines.
- the ring 6 of the ring hybrid consists of a closed slot line on the underside of the carrier substrate 5.
- the connecting arms 1, 2, 3 and 4 cross the ring 6 vertically in the coupling area.
- the connection arms 1, 2, 3 and 4 are distributed over the circumference of the ring 6, which has a circumference of 3/2 ⁇ , as in a conventional 180 ° ring hybrid; i.e.
- connection arm 4 which is preferably connected to an absorber, can be designed in various ways.
- connection arm 4 is connected to a parallel capacitance 10 in microstrip technology on the side projecting into the ring area.
- Fig. 2 the ring hybrid is shown in section.
- the slot line 6 is embedded in the conductive layer 7.
- the characteristic impedance of the microstrip line is preferably chosen to be 50 ⁇ . This results in a characteristic impedance of 71 Q for the slot line.
- connection arms 1, 2, 3 and 4 are distributed on the circumference of the ring 6, which is constructed using slot line technology, each at a distance of ⁇ / 4.
- the connecting arms cross the ring 6 again vertically.
- the connecting arms 1, 2 and 3 also project into the ring area by one ⁇ / 4 piece each.
- the ring 6 in slot line technology on the underside of the carrier substrate 5 has slot lines with different widths.
- the width b1 of the slot line is selected so that that they have a wave impedance of V 2, for example 35 ⁇ .
- the width b2 is selected so that it has a characteristic impedance of Z o , for example 50 ⁇ .
- tuning elements can be attached in the area of the intersections.
