Our “pulse travelingwave tube” amplifiers are equipped with a separate TTL trigger input. The amplifier comprises a special modulator. This modulator is functioning at the cathode voltage making it possible to switch the tube on and off very fast. The cathode voltage is higher than normal due to which a very high power can be reached within a pulse duration. For this reason these special amplifiers can operate with a maximum duty-cycle of 6 [%]. In the “off” period only very low noise is present.

In the frequency range of 1 – 18 [GHz] the amplifiers are available with maximum output power within the pulse of 1 – 8 [kW].
