Schaltung zur Verminderung von Hochfrequenzverlusten in Anodenschutzwiderständen bei Gegen- taktsendern.
EMI1.1
brückung Hochfrequenzverluste in den Anodenschutzwiderständen ganz zu vermeiden. Eine der Fig. 1 analoge Anordnung für Gegentaktsender zeigt Fig. . Auch hier ist wieder der Nachteil vorhanden, dass die Schutzwiderstände für diejenige Störwelle. deren Bahn über die Maschinen-
EMI1.2
Mitte der beiden Kondensatoren Cg. die in diesem Falle dann zu einem einzigen Kondensator zusammengefasst werden können, nicht mehr an Kathode gelegt wird (Fig. 3).
Gleichzeitig ergibt sich durch diese Schaltung eine Verbilligung der Kondensatoren C2. da diese betriebsmässig nun keine Gleichspannung mehr führen. während sie im Falle der Schaltung nach Fig. 2 dauernd an der vollen Gleichspannung liegen. Diese Kondensatoren müssen lediglich für eine Prüfspannung gleich der Anodengleichspaul1ung gebaut werden, da diese Spannung an den Kondensatoren infolge eines Röhrenüberschlages auftritt. Bei Verwendung von mehreren parallelen Röhren pro Seite des Senders werden die Drosseln je zweier gegenüberliegender Röhren durch einen Kondensator zusammengefasst, wie es z. B. Fig. 4 für zwei Röhren pro Seite zeigt.

Circuit for reducing high frequency losses in anode protection resistors in push-pull transmitters.
EMI1.1
bridging to avoid high frequency losses in the anode protection resistors entirely. An arrangement for push-pull transmitters analogous to FIG. 1 is shown in FIG. Here, too, there is the disadvantage that the protective resistances for that interference wave. whose path over the machine
EMI1.2
Middle of the two capacitors Cg. which in this case can then be combined to form a single capacitor, is no longer connected to the cathode (Fig. 3).
At the same time, this circuit makes capacitors C2 cheaper. since these no longer carry direct voltage during operation. while in the case of the circuit according to FIG. 2 they are constantly at the full DC voltage. These capacitors only have to be built for a test voltage equal to the DC anode circuit, as this voltage occurs on the capacitors as a result of a tube flashover. When using several parallel tubes per side of the transmitter, the throttles of two opposite tubes are combined by a capacitor, as is the case, for example, in FIG. B. Fig. 4 shows for two tubes per side.
