CV114 X-band TR cell
|
This cell measures 65x33x95mm overall. |
The CV114 was the first production X-band TR cell, devised in early 1942.
Due to the urgent need the resonant cavity was bored from a brass block
with circular lead glass windows sealed in copper and soft soldered into
place. Because of the soft solder construction the cell could not be outgassed
effectively before the argon/water vapour mixture was introduced. It was
being made in quantity by December 1942 and continued to 1944. It was
superseded by the CV221.
Nominal operating frequency |
9375MHz |
Min DC priming voltage |
-1000V |
Continuous priming current |

The cell has a filling of water vapour to a pressure of 6mm/Hg and Argon
to 3mm/Hg.
The CV specification carries the warning that the TR cell may be damaged
if tuned over its full range more than 5 times. |
