Summary

[edit]
Description
Deutsch: FMCW-Radar: geöffneter Topf- bzw. Leitungskreis mit Scheibentriode (GS13-1)
:

1 - Trimmer und Frequenzhub-Justage / trimmer for mid frequency and sweep
2 - Scheibentriode GS13-1 / disc tube
3 - Auskoppelschleife / coupling loop

English: Microwave cavity of a Russian military frequency modulation, continuous wave (FMCW) radar with cover removed. Inside the cavity is visible the top of the GS13-1 triode vacuum tube which generates the microwaves. It uses high frequency "lighthouse tube" construction; the contacts are in the form of cylindrical rings to reduce parasitic inductance and capacitance. Labeled parts:

1. A setscrew that functions as a "trimmer" capacitor with which the frequency can be adjusted.
2. The top of the lighthouse tube. The top button is the plate (anode) contact which in operation makes contact with a terminal attached to the cover.

3. A wire "coupling loop" from which the output power is taken.
