Powerful generator triode ГУ.21Б in glass-to-metal design with a directly heated tungsten thoriated carbide cathode, external copper anode and forced air cooling.
Designed to amplify the power and generate high-frequency oscillations at frequencies up to 26 MHz with an output power of at least 15 kW.
The ГУ-21Б triode is used to work in circuits with a common grid or in circuits with neutralization in stationary radio engineering devices of wide application.
Produced in metal-glass design.
Working position – vertical, anode down.
– anode – air at least 800 m3/h;
– cylinder – air at least 60 m3/h;
– legs – air not less than 60 m3/h.
Overall dimensions of triode ГУ-21Б:
– lamp height – no more than 355 mm;
– diameter of a lamp – no more than 145 mm.
Weight no more than 8 kg.
Deciphering the marking of the triode:
ГУ – a letter that determines the type of lamp: GU – generator lamps with a generation frequency of 30 to 300 MHz;
21 – the number of serial number of the development of this type of lamp;
Б – a letter indicating the type of forced cooling: Б – air.
