Abstract
A modulator 200 is based around a switching circuit 212 and a pausey stub balun 210. The balun 210 has a distributed resistance 232 to ground. The balun may be implemented as a strip line device (FIG. 5b).
Claims11
Signal combining apparatus comprising terminal means, switching means, and balun means, wherein the balun means is connected via the switching means to the terminal means and ground, the switching means being such that when a control signal is supplied to the balun means, the switching means alternately connects the balun means to the terminal means and to ground to generate an output signal related to an input signal in the terminal means.
A method of combining signals using apparatus comprising balun means connected via switching means to terminal means and ground, the method comprising supplying an input signal to the terminal means, and supplying a control signal to the balun means to alternately connect the balun means via the switching means to the terminal means and ground so that an output signal is generated in the terminal means.
Signal combining apparatus substantially as hereinbefore described with reference to FIG. 2 or FIG. 5.
