Definitions
- the present invention relates to a balun, consisting of interconnected planar cables, one end of a first, between a second and a third line running line as unbalanced signal input is used and the other end this first line is contacted with ground and respectively one end of the other two leads is a balanced one Signal input forms.
- Symmecrierglieder put in a known manner transitions between symmetric and unbalanced Transmission lines ago. From a symmetrical line one speaks, if the signal transmitted over it as Reference potential does not have the mass. On the other hand is one unbalanced transmission line unilaterally grounded contacted, so that a transmitted signal over the Has ground as a reference potential. Baluns of this type are used e.g. at the inputs and outputs of Double balanced mixers or amplifiers or modulators etc. used. One of three coupled planar wires existing balun is known e.g. from J.
- From EP 0 844 684 A1 is a balun with three planar lines known in which one end of a first, between a second and a third Lead running line as unbalanced gate serves and the other end of this first line with Mass is contacted. Two adjacent ends of the second and third line form symmetrical gate, and from the other two ends the second and third line is one with ground and the other connected to the unbalanced gate.
- the invention is based on the object Specify balun of the aforementioned type at with the simplest possible means a DC decoupling is realized.
- the stated object is achieved with the features of claim 1 solved.
- the DC decoupling is realized by that of the second and third line not serving as gates Ends are capacitively coupled together.
- the Capacitive coupling of the line ends in a very simple way and be realized either by the fact that the ends the second and third line with line sections are connected, which over a predefinable length run side by side or in that the ends of the second and third line over one or more Capacitors are connected together. It is appropriate with the third line to connect a capacity in series. This capacity improves the symmetry between the symmetrical gates. It serves to balance the Phase difference to 180 °.
- the balun shown in Figure 1 consists of three adjacent and coupled with each other planar lines 1, 2 and 3.
- the coupling length of these three Lines correspond to about a quarter of the middle Operating wavelength of the balun.
- the first line 1, between the other two lines 2 and 3 runs, is contacted at one end to ground. Is to in the substrate on which the leads are applied, a via 4 to the ground plane on the Provided underside of the substrate.
- the opposite End of this first line 1 forms an unbalanced gate 5.
- the this unbalanced gate 5 adjacent end of second line 2 is a first gate for symmetrical Signals and the second gate 7 for balanced signals is located at the end of the third line 3, which is the Ground terminal of the first line 1 is adjacent.
- the gates 6 and 7 opposite ends of the second conduit 2 and the third line 3 are each with a line section 9, 10 connected.
- the coupling length of the two line sections 9 and 10 is chosen so that a desired capacitive coupling between the ends of the two lines 2 and 3 is formed. These capacitive coupling of the two lines 2 and 3 causes that the balun is DC-decoupled.
- FIG. 2 shows a balun, which is shown in FIG Principle has the same structure as the balun Figure 1 and therefore also the same reference numerals having.
- the shown in Figures 1 and 2 Distinguish embodiments of a balun itself by the kind of the capacitive coupling between the Ends of the two lines 2 and 3. While according to the Embodiment in Figure 1, the capacitive coupling by a line coupling between the line sections 9 and 10 takes place, are at the balun of FIG 2, the two line sections 9 and 10 over two as Concentrated components performed capacitors C2 and C3 linked together.
