Definitions

  • the invention relates to a high-frequency switch according to the preamble of the main claim.
  • High-frequency switches of this type are known as so-called.
  • Crossovers or diplexers consist of a low-pass branch, via which high-frequency signals with a frequency up to the cut-off frequency of the low-pass filter can be transmitted to a common output, and a high-frequency branch, via which high-frequency signals of frequencies above this low-pass cutoff frequency can be transmitted to the output.
  • Switchable crossovers are known in which, for example via PIN diodes, the cut-off frequency of the high or low pass is switchable so that the frequency ranges of the high and low pass do not overlap (eg U.S. Patent 6,411,176 ). These known crossovers are circuitry very complex, especially for applications at very high frequencies in the GHz range.
  • the high-frequency switch according to the invention the high-pass usual in crossovers is avoided, the high-frequency signals above the cut-off frequency of the low pass are supplied only via electronic switches, preferably PIN diodes. Additional switching elements in the high-frequency branch are superfluous. Only the supply of low frequencies to the cutoff frequency occurs in the high-frequency switch according to the invention nor via a low-pass filter, which is preferably additionally switchable so that when the high-frequency branch is switched on, the low-pass filter only acts as a throttle for the separation of low-pass branch and high-frequency branch.
  • Fig. 1 shows a high-frequency switch according to the invention, with the optional high-frequency signals from low frequencies to a predetermined cutoff frequency (for example, up to 3 GHz) from the input E1 to the output A can be switched and high-frequency signals of frequencies above this cutoff frequency of the low pass (for example, about 3 GHz) from the input E2 to the common output A.
  • a predetermined cutoff frequency for example, up to 3 GHz
  • high-frequency signals of frequencies above this cutoff frequency of the low pass For example, about 3 GHz
  • the input E1 so for example optional RF signals of a signal generator with a frequency range of low frequencies up to 3 GHz or the input E2 RF signals in a frequency range of 3 to 6 GHz to the output A through-connected.
  • the low-frequency branch between input E1 and output A consists in a known manner of a low-pass filter TP, constructed in the embodiment of the two parallel capacitances 12, 13 and the series inductors 10 and 11.
  • the high-frequency branch between input E2 and output A consists of only one switchable PIN diode 30.
  • the voltage applied to the node A leading to the node K inductance 11 of the low-pass filter is dimensioned so that it acts as a throttle for the high-frequency path when the PIN diode 30 is turned on and so the low-pass filter TP and its input E1 from the high-frequency Input E2 disconnects.
  • control lines required for switching the PIN diode 30 ON and OFF are not shown in the exemplary embodiment, they are designed in a conventional manner and dimensioned such that they do not disturb the direct switching through of the high-frequency signals from the input E2 to the output A.
  • the inductance 11 can assume a high value that is unsuitable for its realization.
  • this advantageous structure of a high-frequency switch of FIG. 1 parallel to the inductor 11 via a PIN diode 15 switched on and off further inductor 14 is arranged.
  • the PIN diode 15 is switched together with the PIN diode 30 of the high-frequency branch so that when the PIN diode 30 and thus supply of a high-frequency signal via the input E2, the PIN diode 15 is turned OFF and thus the inductance 14th is switched off and only the inductor 11 remains switched on.
  • the PIN diode 15 has no disturbing influence on the low-frequency signal path, since it leads from the input E1 via the inductors 10 and 11.
  • Fig. 2 shows yet another embodiment of a high-frequency switch according to the invention.
  • the high-frequency branch consists in Fig. 2 not only of a single input E2 with an associated switching PIN diode 30, but may be composed of several parallel-connected high-frequency branches E2 to En with corresponding PIN diodes 30 to 40. In this way, one of several different high-frequency signals to the common output A can be fed via the inputs E2 to En either.
  • the invention is not limited to the illustrated embodiments.
  • PIN diodes are mentioned, but other electronic switches such as field effect transistors or the like could be used.
  • PIN diodes have a lower limit frequency in the MHz range, which does not interfere with their use as electronic switches for switching through the high-frequency branches via the inputs E2 to E n, however.
