“…Thales has successfully developed an 80-W Q-band (37.5–42.5 GHz) TWT with a gain of 80 dB and a saturated efficiency of around 50% [ 70 ]. The next step for reaching an even higher instantaneous bandwidth and thus higher transmission speeds will be to use W-band (71–76 and 81–86 GHz) [ 71 ].…”

The application of radio frequency (RF) vacuum electronics for the betterment of the human condition began soon after the invention of the first vacuum tubes in the 1920s and has not stopped since. Today, microwave vacuum devices are powering important applications in health treatment, material and biological science, wireless communication-terrestrial and space, Earth environment remote sensing, and the promise of safe, reliable, and inexhaustible energy. This article highlights some of the exciting application frontiers of vacuum electronics.

“…Fig.1. Simulations of the output power at various input powers and frequencies for an 80W Q-band tapered helix TWT[11] with DIMOHA. It took 22 minutes per point with 16 processors for a numerical resolution of ±0.005 W. On a small computer with 4 processors, it took 16 minutes per point for a resolution of ±0.25 W.…”

We presented at previous IVEC conferences a new model for traveling-wave tubes (TWTs). Since then, we used this model to build the DIMOHA algorithm as an alternative to current particle-in-cell (PIC) and frequency domain codes. Its validity is assessed against these codes and against measurements from several TWTs. We present simulations for an 80 watts TWT in Q band presently in development. An industrial version of DI-MOHA is under construction for the design and characterization of TWTs.
