Definitions

  • the invention relates to a measuring coupler for acting upon a test object with a measuring signal, in particular within an ultra-wideband frequency range.
  • Electronic measuring devices for microwave technology usually have to be designed in an ultra-wideband manner in order to cover all possible applications of the customers.
  • the lower frequency limit is then e.g. at 10 MHz and an upper frequency limit at 60 GHz.
  • the generation and processing of such a frequency range is split internally into several sensible subranges, which are ultimately combined with each other at the front of a meter. Such a combination can be done in many ways.
  • the use of couplers has proven to be the best solution.
  • the US 2008/0094072 A1 shows a system to detect the response of an electronic network in the frequency domain. It comprises a signal source and a signal path to the network under investigation (DUT). Via parallel directional couplers, forward and backward signals are filtered out and can be processed in a switchable frequency-dependent manner. Disadvantages include the already mentioned unfavorable electronic properties of a switch.
  • the US 2003/0214365 A1 shows a directional coupler for a high-frequency amplifier that works in three frequency bands.
  • the disadvantage is the limited frequency range in that the structure works.
  • the invention is based on the object to provide a measuring coupler, which supplies the signals of a lower and an upper frequency range to a measurement object.
  • the waveguide connection is preferably connected to a waveguide.
  • the waveguide is preferably connected to a waveguide-band conductor junction.
  • the waveguide band conductor transition is preferably connected to a second band conductor.
  • the waveguide-to-band transition converts measuring signals of the upper frequency range of waves preferably guided in the waveguide into waves guided on the second band conductor. The conversion of a guided wave in the waveguide to a guided on the stripline wave is achieved with little effort.
  • the first coaxial terminal is preferably connected to a first ribbon conductor coaxial conductor junction.
  • the first ribbon conductor is preferably connected to the first ribbon conductor coaxial conductor transition.
  • the first band-conductor coaxial conductor transition preferably converts lower frequency range measurement signals from coaxially guided waves Waves rippled on the first bandline. The conversion of a coaxially guided wave into a guided on the stripline shaft is thus achieved with little effort.
  • the first band conductor and the second band conductor form a feedforward coupler.
  • the feed forward coupler feeds measurement signals of the lower frequency range or of the upper frequency range on the first band conductor to the measurement object.
  • the measured object on the first strip conductor either a signal from the lower or from the upper frequency range can be supplied.
  • the measuring coupler further includes a second coaxial connection.
  • the measurement object is connected by means of the second coaxial connection.
  • the second coaxial terminal is connected to a second ribbon conductor coaxial conductor junction.
  • the first band conductor is connected to the second band conductor coaxial conductor junction.
  • the second stripline coaxial conductor transition converts the measurement signals from waves carried on the stripline into coaxially guided waves and preferably feeds them to the second coaxial terminal. The conversion of guided on the stripline waves in coaxial waves is thus achieved with low production costs.
  • the measuring coupler preferably also has a third coaxial connection and a fourth coaxial connection.
  • the third coaxial terminal and the fourth coaxial terminal are preferably connected by means of a third band conductor.
  • the third band conductor and the second band conductor preferably form one Backward coupler.
  • the third coaxial terminal preferably outputs signals which are proportional to signals reflected by the measurement object.
  • the fourth coaxial terminal preferably outputs reference signals which are largely proportional to measurement signals of the lower frequency range.
  • the third coaxial terminal is preferably connected to a third band conductor coaxial conductor junction.
  • the third band-conductor coaxial conductor transition converts waves guided on the band conductor into coaxially guided waves.
  • the fourth coaxial terminal is preferably connected to a fourth bandline coaxial conductor junction.
  • the fourth co-conductor coaxial conductor transition converts waves guided on the ribbon conductor into coaxially guided waves.
  • the third coaxial terminal and the fourth coaxial terminal are preferably connected by means of the third band conductor coaxial conductor transition, the fourth band conductor coaxial conductor transition and the third band conductor.
  • an attenuator is inserted in the third band conductor. This avoids that reflections of the measurement setup surrounding the measuring coupler transform via a cable connected to the fourth coaxial connection to the directional coupler and impair its directivity.
  • the band-conductor coaxial conductor junctions preferably have compensations which provide for a low-reflection conversion of the waves guided by the ribbon conductors into coaxially guided waves. This ensures a very low-reflection conversion.
  • the first strip conductor is preferably designed in two parts.
  • the two parts of the first strip conductor are preferably intermeshed at a connection point. The separation into two parts takes place for manufacturing reasons. So a very low production cost is achievable.
  • the second band conductor is preferably connected to an absorber. A secure operation of the feedforward coupler is guaranteed.
  • the band conductors preferably have a characteristic impedance of 50 ⁇ . So a simple integration into existing systems is possible.
  • the measuring coupler has a housing, which is preferably composed of at least two housing parts. All band conductors are preferably arranged in the housing.
  • the housing serves as a shield and / or counterelectrode for the strip conductors. Furthermore, a mechanical protection of the band conductor structures is achieved with low production costs.
  • Capacitive disturbances of the strip conductors caused by the fastening of the strip conductors in the housing are preferably eliminated as far as possible by compensations.
  • a secure positioning of the band conductor is achieved with very low electromagnetic interference. This further reduces transmission disruptions.
  • At least part of the inside of the housing is preferably lined with an absorber material.
  • the feed forward coupler and the feedback coupler are preferably implemented in stripline technology. An interface between different waveguide types that would degrade the directivity of the backward waveguide is thus avoided.

  • signals fed to the coaxial connection 17 of the second section 16 of the first strip conductor 1 are coupled with low attenuation to the connection 23 of the third strip conductor.
