Definitions

  • the invention relates to a connector for RF signals, preferably to a U-link connector for use in a broadcast patch panel.
  • the antenna cables are subject to long-term degradation or failure due to electrical, mechanical and environmental stress.
  • a monitoring of the antenna cables and/or antennas is desired.
  • a standard method for monitoring the antenna cables is to disconnect the transmitters during maintenance and to measure the electrical properties of the cables.
  • a disconnection of a transmitter may be done by a U-link connector as disclosed in DE 37 06 989 A1 or US 6,139,369 , which may be attached to a patch panel. This method does not allow for a continuous monitoring of the cables and requires a shutdown of the station.
  • the problem to be solved by the invention is to provide a means and a method for testing and/or monitoring antenna cables in radio transmission and communication systems. There should be a simple and cost effective way of refurbishing existing systems. Furthermore it is preferred, if a continuous monitoring even curing operation of the system it possible
  • a first embodiment relates to a U-link connector for use in a broadcast patch panel, the connector having the function of a test adapter and comprising electrical or electronic components for coupling a test device to the antenna cable to be monitored.
  • the U-link connector comprises a filter circuit for coupling DC signals to the antenna cable.
  • the connector may have the function of a bias tee.
  • Such a U- link connector can easily be attached to a broadcast patch panel, which usually is provided between the transmitter(s) and the receiver(s) of a radio station.
  • simply existing old U- link connectors are replaced by the new U- link connector with integrated electrical or electronic components. This allows for a very simple and inexpensive refurbishment of existing stations. It is no more necessary to alter existing cables or waveguides.
  • a U- link connector has a first RF connector and a second RF connector. Both RF connectors preferably are coaxial connectors and further preferably are of the same type. Most preferably, they are male connectors.
  • the RF connectors are connected by a RF line within the U- link connector, preferably a coaxial line.
  • This coaxial line may have an outer conductor, which may be formed by or within the housing of the U- link connector.
  • the outer conductor of the U-link connector connects the outer conductors of the RF connectors.
  • the U- link connector comprises a coaxial line, it may also comprise a strip line or any other line suitable for transmission of RF signals.
  • the inner conductor comprises and/or forms a series capacitor for coupling RF or high frequency signals between the first RF connector and the second RF connector, while blocking DC or low-frequency signals.
  • the capacitor may be a gap between conductor parts, a stack of plates or any other capacitive element.
  • the inner conductor comprises a first inner conductor section and a second inner conductor section, which preferably are flat metal plates. They are arranged, in close proximity parallel with each other to form the coupling capacitor.
  • a dielectric material is provided between the first inner conductor section and the second inner conductor section. This material may be PTFE or Polyimide or any other dielectric material.
  • the inner conductor sections may have bent portions for increasing coupling and mechanical stability.
  • the inductor connected between the first RF connector and a first test connector.
  • the first test connector may be used for connecting a test and/or measuring and/or monitoring device.
  • the purpose of the inductor is to allow coupling of DC or low frequency signals between the test connector and the first RF connector for blocking RF or high-frequency signals.
  • the embodiments shown herein have to provide at least a low VSWR and a low attenuation between the first RF connector and the second RF connector. Furthermore, they should be able to transfer high RF power levels as these are generated by the transmitters.
  • first and second RF connectors relate to first and second RF connectors. It is obvious, that the connectors may be exchanged, if necessary. Furthermore, there are no limitations on the specific type of RF connectors.
  • inventions shown herein may also be applied to antennas, which are only used for receiving signals and therefore handle lower power levels.
  • a further embodiment relates to a patch panel in a radio station comprising at least one U- link connector as disclosed herein.
  • a method for coupling a DC or low frequency signals to an antenna cable and/or antenna comprises the steps of connecting a U- link connector as described above to a patch panel being connected to the antenna cable and coupling the DC or low-frequency signals via the U- link connector to the antenna.
  • the method includes coupling RF signals from the second RF connector to the first RF connector, most preferably by means of a serious capacitor.
  • a method for refurbishing of radio stations or equipment of radio stations includes the step of replacing an existing U- link connector by a U- link connector as disclosed herein to provide access for test equipment to an antenna and its cable.
  • the method further comprises the step of connecting a test device to a first test connector of the U- link connector.
  • testing of the antenna and its cable may be done by the test device.
  • a housing 10 holds a first RF connector 40 and a second RF connector 50.
  • the housing further forms an outer conductor holding an inner conductor 60 for guiding a RF signal between the second RF connector 50 and the first RF connector 40, preferably in a TEM mode. It is preferred, if a transmitter (not shown here) is connected to the second RF connector 50, while an antenna connected by an antenna cable (not shown here) is connected to the first RF connector 40.
  • the first RF connector 40 has an outer conductor 41 and an inner conductor 42.
  • the second RF connector 50 has an outer conductor 51 and the inner conductor 52.
  • the inner conductor 60 forms a coupling capacitor 20 for coupling RF and high-frequency signal as well as blocking DC and low-frequency signals between the RF connectors.
  • a first inner conductor section 61 connected to the inner conductor 42 of the first RF connector 40 and a second inner conductor section 62 connected to the inner conductor 52 of the second RF connector 50.
  • the first inner conductor section 61 and the second inner conductor section 62 are metal plates, which are arranged, in close proximity parallel with each other to form a coupling capacitor 20.
  • a dielectric material 63 is arranged between the first inner conductor section 61 and the second inner conductor section 62. This material may be PTFE or Polyimide.
  • the coupling capacitor 20 may also be a separate component connected between the first inner conductor section 61 and the second inner conductor section 62. It is obvious, that the inner conductor 60 is split to prevent a short circuit of the capacitor.
  • An inductor 30 is arranged in close proximity to the first RF connector 40. Although the inductor may be anywhere else, this results in a compact mechanical design with good RF characteristics.
  • the inductance is wound to a coil being supported by a coil core 35.
  • Its first coil connecting line 31 is connected to a first test connector 33.
  • a second coil connecting line 32 at the opposite end of the coil is connected to the first connector inner conductor 42 and to the first inner conductor section 61 of inner conductor 60.
  • FIG. 2 shows a sectional view at the portion of the U- link connector close to the first RF connector 40.
  • a load connector 34 can be seen which preferably is terminated by a load.
  • a specific connector (not shown here) may be used.
  • Figure 3 shows a top view.
  • the short-circuit connector 35 can be seen on top of coil housing 36.
  • Section line A-A relates to the sectional view of figure 1
  • section line B-B relates to the sectional view of figure 2 .
