Definitions
- the invention relates to a circuit for dividing or merging high-frequency powers according to the preamble of claim 1.
- Circuits for dividing or merging high-frequency powers are known, for example, as so-called bridge circuits or as Wilkinson couplers. They are mainly used in high frequency technology for the parallel connection of high frequency transmitters or antennas.
- the circuit is arranged, for example, in an elongated housing, on one end of which the so-called sum mentor (entrance) and at the opposite end, for example, a first individual gate and the second individual gate can be provided on a transverse side adjoining it at right angles.
- a power distribution is realized by different resistors on the single gate (parallel connection of different single gate resistors).
- the first single goal remains unchanged.
- the second single gate is e.g. subjected to a ⁇ / 4 transformation.
- the power division according to the prior art is implemented by means of a different impedance Z (“ ⁇ / 4 transformation”).
- the power sharing has an effect on the input.
- these cannot be set variably, so that different types and devices have to be provided for the different power division ratios.
- a circuit for dividing or merging high-frequency powers in which a main line is connected between an input and a first output port, from which a branch line branches off at a branching part.
- an adjustable decoupling element is provided, which determines the size of the diverted power by changing the capacitance of a capacitor connected in the branch line.
- the decoupling element can be adjusted in a narrow band, ie only the measuring branch is adapted. This decoupling element however, especially at higher frequencies, it affects the impedance of the main line.
- the circuit arrangement according to the invention is not only new, but is extremely surprising in its overall structure and in view of the advantages that can be achieved thereby. Because by means of the circuit arrangement according to the invention, it is possible in a preferred embodiment to implement a variable power distribution without the input impedance changing in the process. According to the invention, this is achieved by a combination of variable coupling capacitances and a variable stub line, both elements preferably having a common connection. service element can be varied.
- the power is preferably distributed in such a way that a further RF line branches off from a continuous RF line and is capacitively coupled.
- a transformation for the resistance adjustment at the input or sum gate is implemented without this - as mentioned - having an effect on or a change in the input impedance.
- Frequency compensation or frequency predistortion is effected on the decoupled branch.
- a change in the power distribution can now be carried out by problem-free adjustment of an adjusting or adjusting element provided, and this has no effect on the input impedance.
- not only different type devices, but only a differently adjustable type are now required for different power sharing ratios.
- the circuit arrangement according to the invention is therefore to be installed for a wide variety of power branches in an HF broadband network, for example in the case of signal transmission in a building for the various power branches in the individual floors, building complexes, etc. Only by rotating an input element can the corresponding power branching be carried out the desired power distribution can be set easily. If you also consider that when wiring a house, a large number of distributors are usually necessary to receive the signals that are fed in To divide (for example in the basement) onto a large number of lines and, for example, to perform a power distribution over different branch lines with possibly always different power proportions on the individual floors of a house, the advantages according to the invention become all the clearer. This is because, according to the invention, only a single circuit device is required for, in particular, stepless power distribution, which can be easily adjusted to the current requirements, which can now be used to easily compensate for the different cable lengths, cable attenuations, etc.
- the power distribution according to the invention is preferably implemented using a balancing element which is arranged in a variable position.
- the change in position changes the coupling of the power into the branching line and, according to the invention, simultaneously compensates for the change in resistance caused by the changed coupling.
- the mechanically position-adjustable adjustment element can be electrically conductive, but it does not have to be. In the same way, for example, a dielectric balancing element can be used.
- the adjusting element can be arranged in an axial extension to the branching line, the main line running between the entrance and the further exit gate (that is, between the sum and the further single gate) being arranged transversely thereto.
- the desired modified decoupling can preferably be carried out by means of a mechanically adjustable probe, the axial position of which can be changed, for example, by radial rotation.
- the adjustment element can also be set differently, for example, by a different type of adjustment mechanism.
- a further preferred exemplary embodiment provides that the actuator on the circuit housing can be adjusted linearly.
- the adjustment movement is preferably carried out in the axial longitudinal direction of the circuit housing. Via this adjustment movement, the adjustment movement, i. preferably the linear adjustment movement of the adjustment element is realized and implemented, the adjustment movement of the adjustment element taking place perpendicular to the adjustment movement of the actuator.
- the entire arrangement has the further advantage that, for example, a clearly visible scale can be attached, it being possible to read exactly which power distribution is currently set, depending on the adjustment position of the adjustment element.
- the translation between the actuator and the balancing element can also be non-linear if this is desired. Otherwise, a linear translation can be implemented at any time.
- the bandwidth of the decoupling unit can be very large, for example 45%.
- the circuit arrangement according to the invention can be constructed coaxially. However, it can also be implemented using discrete components or in circuit board technology.
- circuit according to the invention can also comprise a plurality of variable coupling elements for constructing an n-fold distributor.
- the circuit according to the invention for dividing or combining high-frequency powers, with a main line or main line (7) connected between an input and a first output port (1, 3), and a branching line branching from the main line at a branching point (9) and A branch line (11) leading to a second output gate (5) is therefore preferably characterized in that an adjustment element (61), which is adjustable or can be installed and removed differently, is provided, which changes the capacity of at least one in the branch line (11) Capacitor (C 2> C 3 ) and / or change in the electrical length of a stub line (37) coupled to the branch line (11) can be changed in such a way that with the changed size of the branching power, the change in resistance caused by the changed power distribution also occurs is compensable.
