Generator tetrode GU-36B-1 for broadband amplification of high-frequency oscillations at frequencies up to 250 MHz in circuits with a common grid or a common cathode.
The design is ceramic-metal, with ring electrode leads.
Cooling - forced air:
— anode — not less than 1200 m3/h,
— legs not less than 200 m3/h.

1. Filament current 120 ± 5 A.
2. Cathode emission current (at Ua=400 V), not less than 30 A.
3. Anode current (at Uc1=0), not less than 4 A.
4. Grid reverse current (at Uc= -300 V, Ua=0) ≤ 300 μA.
5. Vibrational power (at a frequency of 250 MHz and a band of 8 MHz), not less than 10 kW.
6. Slope 83 ± 13 mA/V.
7. Interelectrode capacitances:
– input 150pF,
– output, no more than 24 pF,
– throughput 0.6 pF.
8.Weight of the triode: 11kg.
9. Heating voltage 8.3V.
11. Power dissipated by the anode 15 kW.
12. Operating ambient temperature up to 60 C.
13. Durability, not less than 2000 hours.
