摘要： A transition device for connecting a coaxial cable to an integrated microwave circuit (MIC) composed of planar lines disposed on a substrate, the device being composed of a coaxial connector having a protruding inner conductor, a tuning screw disposed to form a variable capacitor with the protruding conductor of the coaxial connector and arranged to be adjusted to control the electrical parameters of the device, an intermediate dielectric carrier carrying a planar intermediate line connected to the inner conductor of the connector, the intermediate carrier forming a fixed unit with the coaxial connector and being disposed between the connector and the (MIC) substrate, a housing supporting the fixed unit and the substrate, and two metal bands connecting together the planar intermediate line and the planar line of the microwave circuit and the bottom metallization.

摘要： A traveling wave tube transmission amplifier arrangement, including the series connection of a predistortion circuit, a preamplifier with limiter circuit and a traveling wave tube amplifier, which is provided with several stabilizing circuits. To limit the output power, a signal which is a measure of the output power of the traveling wave tube, e.g., a signal proportional to the collector current of the traveling wave tube, is fed to a threshold controller which governs a variable attenuator provided at the input of the transmission amplifier arrangement. Moreover, to provide compensation for aging effects, a remote control signal, which is determined on the basis of an intermodulation measurement, is fed to the preamplifier with limiter circuit.
