    Generating Thetrode in metal-ceramic performance with separate cathode.
    Air cooling.
    Tube is designed for amplification of high frequency pulses with short off-duty factor by driving of 2nd grid
    .
    Minimum life time = 1000 hours.
    Limit values:
    Anode voltage = no more than 3700 V
    Anode voltage with 400 and more off-duty factor = no more than 4000 V
    2nd grid voltage = no more than 800 V
    2nd grid voltage with 400 and more off-duty factor = no more than 850 V
    Anode voltage without anode current (closed tube) = no more than 4200 V
    1st grid bias voltage = -100 V ... 0 V
    2nd grid blocking voltage = no more than -60 V
    Heater voltage = 6.0 ... 6.6 V
    Anode pulse current = no more than 2.25 A
    1st grig pulse current (Ug2=800 V) = no more than 0.9 A
    2nd grig pulse current = -0.3 ... 0.3 A
    Anode dissipation = 100 Watt
    1st grid dissipation = 3 watt
    2nd grid dissipation = 3 watt
    Maximum driving power in pulse at f=1667 MHz = 225 Watt
    Optimum driving power in pulse at f=1667 MHz = 200 Watt
    Maximum driving power in pulse at f=3000 MHz = 400 Watt
    Output power at f=1667 MHz = at least 3500 Watt
    Output power at f=3000 MHz = 1365 ... 3000 Watt
    Off-duty factor at f=1667 MHz = at least 80
    Off-duty factor at f=3000 MHz = at least 200
    Pulse duration = no more that 15 mks
    Heating time = no more that 90 sec
    Maximum allowable temperature of the tube = 200 degree of Celsius
    After payment is confirmed (1-2 days) please allow for around 10 business days for shipment.
