The CV4515 ( commercially the K337) is an X-Band reflex klystron oscillator operating between 9 and 10 GHz. The output for a low power transmitter or radar local oscillator is 45 mW. Electrically the tuning range is 24 MHz. The mechanical tuning screw can be seen in the main image.
The KB/Q identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the Q identifies the maker as English Electric Valve Co., Chelmsford.
The output from the resonant cavity is via a WG16 flange (41 mm square).
