Abstract:
The article presents the results of development of a multimode waveguide tract of circular cross-section high-capacity Ka-band for the transmission of the microwave signal from a power amplifier of the transmitter based on gyro- TWT for an antenna system. Waveguide tract developed in the frequency range 33.7-34.3 GHz with input pulse power up to 120 kW, duty cycle up to 8 (average power up to 15 kW) with the most uniform amplitude - frequency and phase - frequency characteristics and minimal losses. The article presents the results of measurements of the designed waveguide tract. The resulting value of the nonlinearity of the phase - frequency range is ±10° and the results of measurement of losses in components and separate segments are presented in the article.
