Definitions

  • SPST switches single pole single throw
  • SPDT switch single pole double throw
  • the switches mentioned contain PIN diodes, but because of their structure they have a reflection loss that is too small and a transmission loss that is too high. Namely, they contain a chip (substrate) which is connected via gold lines, the spacing of which from other conductors is subject to specimen scattering, so that there are joints of the wave resistance coating.
  • supply lines for the control current of semi-titanium switches for freedom from electrical interference are ensured by the fact that supply conductor tracks are provided on the plate in an easily reproducible manner and are designed as blocking filters for the high-frequency energy.
  • the plate 1 will therefore preferably be surrounded by a metallic frame or housing 9, for example made of aluminum, of which a partial section can be seen in FIG.
  • the metallization 2 of the plate 1 on the back is not directly on the frame 9, but there is a spring plate 10 interposed, which fulfills several functions: It serves for electrical contact between the back of the plate 1 and the frame 9, but also for heat transfer from the plate to the frame and finally allows expansion compensation between the Ceramic-made plate 1 and, for example, aluminum frame 9.
  • the clamping of the plate 1 in a frame 9 also enables contacting of the microwave connections at the gates E1, E2, A and the direct current control connections A1, A1 ', A2 by pressing the inner conductor ends of plugs with a pressure piece onto the conductor tracks ending there.
  • the plate 1 can be easily replaced without soldering microwave connections.
  • the DC control connections are preferably soldered on, but can also be contacted with a pressure piece.
  • the use of a plate 1 made of ceramic with conductor tracks, which form microstrip lines, on the one hand enables very good and reproducible electrical values, and on the other hand the best possible heat dissipation from the semiconductor switches via their substrate, the plate and the many contact points of the spring plate 10 on the frame 9 possible.
  • the switch shown can thus absorb the high-frequency power of both transmitters in the event of a failure of the DC control, without being destroyed.
