The GS-9B microwave triode is used for RF voltage generation in external-feedback oscillators designed for continuous operation in the decimeter wavelength range down to 9cm. The triode is available in two variants: with heat sink, for forced air cooling (GS-9b), and without heat sink, for other types of cooling (GS-90b). The GS-9b is physically identical to the GI-6b and GI-7b, but several electrical parameters are different.
