Description
Bekannt ist eine Anordnung, bei welcher eine in Bremsfeldschaltung geschaltete Ultrakurzwellenrohre mit einer in gewöhnlicher Schaltung geschalteten Verstärkerröhre galvanisch verbunden ist, zu dem Zwecke, schwingfähige Kopplungsglieder zwischen den beiden Röhren zu vermeiden.An arrangement is known in which an ultra-short wave tube connected in a braking field circuit galvanically with an amplifier tube connected in a common circuit is connected, for the purpose of avoiding vibratory coupling members between the two tubes.

«5 feldschaltung geschaltete Röhre 2 liefert. In diesem Falle wird zweckmäßig nicht nur das Gitter, sondern auch die Anode der Röhre 1 mit der Kurzwellenröhre 2 galvanisch verbunden und zwar derart, daß die Anode der Röhre 1 mit dem Gitter der Röhre 2 und das Gitter der Röhre 1 mit der Bremselektrode der Röhre 2 verbunden wird.«5 field circuit switched tube 2 supplies. In this case, not only that is useful Grid, but also the anode of the tube 1 is galvanically connected to the shortwave tube 2 in such a way that the anode of the tube 1 with the grid of the tube 2 and the The grid of the tube 1 is connected to the braking electrode of the tube 2.
Da bei der in Bremsfeldschaltung geschalteten Röhre 2 an der Gitterelektrode eine hohe positive Spannung und an der Bremselektrode eine geringe positive oder negative Spannung liegt, und umgekehrt bei der Röhre 1 die hohe positive Spannung an der Anode und die geringe Spannung am Gitter liegt, ist eine Verbindung in der angegebenen Art ohne weiteres möglich.Since the tube 2 connected to the braking field circuit has a high positive voltage and a low positive or negative voltage on the brake electrode Voltage, and vice versa in the case of tube 1 the high positive voltage at the anode and the low voltage on the grid is a connection of the type indicated easily possible.

Die Abbildung zeigt ein Ausführungsbeispiel der Schaltung. Die in bekannter Rückkopplungsschaltung geschaltete Elektronenröhre ι erzeugt eine Wechselspannung, welche direkt an dem Gitter der in Bremsfeldschaltung geschalteten Ultrakurzwellenröhre 2 liegt. Die hohe positive Gleichspannung wird durch die Drossel 3 gleichzeitig der Anode der Röhre 1 und dem Gitter der Röhre 2 zugeführt. The figure shows an embodiment of the circuit. The known feedback circuit switched electron tube ι generates an alternating voltage, which directly on the grid of the ultra-short wave tube 2, which is switched in the braking field circuit lies. The high positive DC voltage is simultaneously the anode through the choke 3 the tube 1 and the grid of the tube 2 fed.
