Definitions
- the invention relates to an antenna filter combiner for connecting a variety of frequency channels a transmitting antenna.
- the base stations of mobile radio systems must be very narrow-band and high-powered frequency channels reactively interconnected and the transmitting antenna be fed.
- the number of frequency channels generally according to the respective expansion stage be modularly expandable and on the other hand every transmission filter on any agreed without loss of quality during operation Channel frequency can be changed at short notice.
- Waveguide branching points such as those made of the essay “Computer-Aided Design of Waveguide Multiplexers” by A.E. Atia, published in “IEEE Transactions on Microwave Theory and Techniques ", March 1974, pages 332 to 336 are known to have been used in satellite and microwave technology proven.
- the partial filters are sent to an am End short-circuited waveguide coupled, however the distances between the coupling levels of the filters from whose frequency positions depend, thus electrically significant and with the filter retuning in the switch as well would have to assume other values.
- the waveguide dimensions for those currently located at 0.9 GHz and 1.8 GHz Mobile radio systems are relatively large and compact Do not allow switch setup.
- the duct switch chains used especially in directional radio technology with circulators such as those from the Essay "Channel Branching Filters for Wideband Radio Relay Systems "by G. Ensslin, H. Herder, R. Schuster in telcom-report 10 (1987), special "Radio Communication", Pages 146 to 151 are known, offer good options of the modular structure.
- An arrangement is also from EP 0 262 391 A2 with several circulators for switching on one each Sender / receiver pairs known.
- the invention has for its object for an antenna filter combiner of the type described at the beginning Solution for a simple setup with low loss transmission filters specify.
- Figure 1 shows a modular antenna filter combiner for a retroactive combination of maximum n ⁇ m transmit frequency channels in the block diagram.
- the direction of signal flow the circulators Z is used so that in the course of Waveguide W1 on local circulators 1 ... ( ⁇ -1) already fed frequency channels at the crossover of the ⁇ .circulator at least approximately totally reflected and possibly with additional crossovers wired circulators ( ⁇ + 1) ... n in the direction of the antenna Ant can be forwarded.
- the waveguide W1 is at its end in front of the first circulator Z1 the resistor R is properly terminated.
- the ⁇ > 2 sub-filters TF of each crossover FW are more advantageous High Q resonators, e.g. Coaxial resonators, helix resonators, hollow tube resonators, dielectric resonators, HTSL resonators. If available the resonators can meet the physical requirements operate with two or more modes, e.g. orthogonal Modes in the hollow tube or dielectric resonator.
- High Q resonators e.g. Coaxial resonators, helix resonators, hollow tube resonators, dielectric resonators, HTSL resonators.
- the ⁇ partial filter TF are concentric and, based on the Resonator axes, parallel to the axis of the apex of the Crossover forming second waveguide W2 arranged.
- the other end of the second waveguide W2 is as Connector prepared or designed so that an immediate, optimally short connection with the third gate one in the first waveguide W1 circulator Z is possible.
- the second waveguide W2 consists of one modified coaxial line. A more detailed constructive The arrangement is shown in FIGS. 6 and 7 shown and will be discussed later in connection with this description of the figures explained in more detail.
- two partial filters TF1, TF2 are provided, which in one case run with their central axes in one plane with the inner conductor of the central coaxial line arranged between them (second waveguide W2), while in the other case the second waveguide W2 is arranged symmetrically to the two sub-filters outside the plane mentioned.
- the radius of the filter resonators is r
- the radius of the outer conductor of the second waveguide is r K.
- the resonators In the area directly opposite the second waveguide W2, the resonators have a filter coupling FA.
- the electrically effective length from the filter coupling FA to the inner conductor of the second waveguide (crossover vertex WS) is designated by x.
- x 2 r K + s, where s is the material thickness between the filter resonator and the second waveguide W2.
- the filter couplings are not shown in the illustrations in FIGS. 2 to 5.
- Figures 6 and 7 show a three-channel crossover in the antenna filter combiner in two sectional views. This represents a particularly favorable solution in terms of Economics and the electrically critical length of the Filter outputs to the switch crest.
- the 3-channel crossovers are implemented in such a way that in a metal block or a metallized plastic block, three blind bores as resonator housing 1 are circumferentially symmetrical to a continuous central bore 3, which represents the outer conductor of a coaxial line forming the second waveguide, in such a way that the minimum wall thickness between the resonators each assumes a small, mechanically expedient value.
- the dielectric resonators DR1, DR2, DR3 are each fixed centrally on thin-walled tube sections 5 made of a suitable microwave insulation material.
- the conductors of the filter decouplings A1, A2, A3 run insulated through bores in the wall between the resonator housing 1 and the central bore 3 and form the physical apex of the crossover at the connection point WS with the inner conductor 4 of the central coaxial line.
- the filter couplings E1, E2, E3 are offset by 90 ° relative to the couplings on the circumference of the resonator housing.
- Asymmetry screws K1, K2, K3 are arranged at 135 ° to the filter coupling and decoupling, with which the bandwidth of the filter is set.
- the central coaxial line has at one end a connection 6 for a circulator with the channels SK1, 2, 3, while on the other side as a residual error compensation at the apex WS (connection point of the filter output lines and the inner conductor of the coaxial line) one shorted at the end without additional space requirement Coaxial line is continued.
- the inner conductor 7 is designed to avoid temperature-related mechanical stresses at the end as a slightly bent wire 8 and connected to a cover 9 covering the entire switch unit, for example by clamping.
- the two-circuit sub- filters of the crossover implemented in this case with dielectric resonators DR are operated with orthogonal HE 11 ⁇ modes.
- the respective blocking filter over the Connection lines between the filter outputs and the second one Waveguide (switch vertex) largely balanced.
- the manufacture of the housing brings electrical advantages Switch arrangement from a single metal block or metallized Plastic block through short and defined connection paths and a minimal number of connection points. Mechanical advantages are a compact and space-saving Construction, the accommodation of the compensation means without additional space requirements and in defined and low tolerance connections.
- the one operated with orthogonal modes dielectric resonator as a highly selective dual circuit filter is particularly advantageous from a high point of view Quality and climate requirements, the desired compactness and the excellent economy in the crossovers current mobile radio systems.
- any sub-filter of the filter combiner to all agreed channel frequencies within the system frequency band is without impermissible Deformation of the filter properties (e.g. by serious Loss of quality or the occurrence of fault modes) achieved that the dielectric resonator DR by two Resonators about half the thickness (in the axial direction) and about is replaced with the same external dimensions, whereby defines at least one of the two resonator halves, e.g. by means of a system-controlled stepper motor, in axial Movable direction and the strength of the Air gap 10 between the two resonator halves ultimately the Center frequency of the two-circuit filter determined.
- This Movability is shown in Figure 6 by the two-way arrow indicated.
