  • Multichannel combiner/divider
    Patent number: 4933651
    Abstract: Disclosed is a device to combine or divide the power values of electromagnetic signals and, more particularly, a device of the radial mode. In a combiner/divider which comprises two metallic disks defining an annular space of propagation, each channel is separated from the adjacent channel by a radial slot which is placed in the lower disk and extends from the central aperture to the peripheral ring. Furthermore, each channel thus defined has a radial ridge. The invention can be applied to transmitters, notably those used in radars.

  • Device to control the output power of a class C amplifier
    Patent number: 4890070
    Abstract: Disclosed is a device to control the output power of an amplifier working in class C mode and comprising at least one bipolar transistor. The bias resistance of the bipolar transistor is made variable through the presence of a field effect transistor, to the gate of which is applied a voltage Vgs, chosen from a set of values that are determined experimentally as a function of the output power to be obtained, the power and frequency of the input signal and the temperature of the bipolar transistor.
