REFLEX Klystron
The 2K45 Vacuum tube is a thermally tuned X-band reflex
klystron. It is a 300V, 32mW out put tube, that ranges from 8.50 to
9.66 GHz. The tuner plate current is 0 to 25mA. The
thermal tuning triode plate is a wall of the resonating
cavity. It is used in frequency-agile radars and tunes
over the entire band in 6 seconds. This tube has a metal
body, like a shortened metal 6L6. It has a coaxial
output through the octal-like base, as in 723A/B tubes
which is also a Raytheon.
