SIEMENS RK25 Reflex Klystron
Luftgekühltes Reflexklystron
Klystron reflex

The RK25 is an air-cooled reflex klystron with resonant cavity for use in modulators and oscillators for frequencies from 3.4 to 4.5 GHz. The klystron delivers an output power of 180 mW.

It was used in telecommunications during the 1960's - 1970's.

Heating: 6.3 V / 1 A - Indirect Heating
