The CV1297 is a radar T/R cell designed to operate at 2.925 to 3.075 GHz. The prototype was the CV2739.The primer electrode is present to maintain a low level ionisation and thus to speed up the main breakdown of the gap when a transmit pulse commences. This breakdown effectively isolates the sensitive receiver input stages from being destroyed by the magnetron transmit energy that can be 500 kW at its peak.The KB/N identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the N identifies the maker as STC, Footscray, pre August 1951.
The copper discs would be sealed into a cavity resonator. The primer supply connects to screw top cap.The wide glass tube envelope is 29 mm in diameter and, including the base, is 126 mm tall.Reference: Data-sheet. Type CV1297 was first introduced in 1955. See also 1955 adverts. |
