The CV2638 is a mercury-argon thyratron with a peak anode current of 6 Amps at 1,250 volts and thus a peak pulse capability of 7.5 kW. This pulse can be repeated at a maximum of 150 times a second. Ideal for a small radar transmitter.
The screening cylinder makes observation of the inner details difficult but a small diameter flat cathode can be seen with the heater below.The classic envelope is 52 mm in diameter, and excluding the IO base pins is 149 mm tall.References: Datasheet. |
