YU-204 Amperex Transmitting Pulse Tetrode (Improved 4PR1000A) (Pull)
The YU204 is a pulse tetrode intended for use in pulse modulator, pulsedamplifier and pulsed-oscillator service. This compact, high vacuum radial-beam tetrode, incorporating a molybdenum anode and non-emitting grids, is recommended for use in new equipments where high voltage, high current, or high duty factor is encountered.
Cooling of the tube is accomplished by radiation from the anode and by circulation of forced-air through the base and around the envelope. Cooling can be simplified by the use of the SK-510 Air System Socket and the SK-506 Air chimney.
The YU204 is specially designed for medical MRI applications where high noise immunity and high stability are required. It is an improved version of 4PR-1000A (Radial Beam Pulse Tetrode).
Maximum ratings for oscillator use are as follows:
Peak DC Plate Voltage: 20 kV
DC Screen Voltage: 2.5 kV
DC Grid Voltage: 1 kV
Peak Cathode Current: 12 A
Plate Dissipation: 1 kW
Screen Dissipation: 75 W
Grid Dissipation: 25 W
Highest Frequency: 110 MHz
Amplification Factor Grid to Screen is: 6.9
Filament Current -at- 5.0 V is: 21.4 A (nom. Filament Voltage is 7.5 V)
