GI-7BT
UHF pulse generator triode
Description
Purpose and application
GI-7BT is a metal-ceramic generator triode for generating and amplifying decimetre-wave RF oscillations. It operates in continuous and pulse modes with anode modulation and is designed for common-grid circuits.
Full descriptionCollapse description
Construction
The defining feature of GI-7BT is its cylindrical finned radiator. The heater supply is 12.0–13.2 V and heater current is 1,925 ± 0,125 A. The tube weighs about 330 g and may be installed in any position.
Operating data
Reference limits include 2.5 kV continuous anode voltage, 9 kV pulse anode voltage, pulse anode current up to 7.5 A, pulse duration up to 10 µs and anode dissipation up to 350 W. The minimum operating wavelength is 9 cm.
Cooling and selection
The radiator requires forced airflow of at least 24 m³/h. GI-7BT must not be selected from appearance alone: compare its full suffix, cylindrical radiator, coaxial contacts and the circuit data stated by the equipment manufacturer.
The operating principle is covered in the vacuum tube article. Related devices are listed under generator and modulator tubes.
