For high frequency signals phasenumtaster above 100 ghz

摘要

Binary digital phasenumtaster for the production of high-frequency signals in the frequency range above 100 ghz, comprising– a driver amplifier, the input of a digital baseband signal can be supplied, and the is formed, to reinforce the baseband signal,– a single-pole change-over switch, the on an oscillator input an oscillator signal in the frequency range above 100 ghz can be supplied, and the a control signal input as well as a first and a second signal output, and which is formed, the amplified baseband signal to the control signal input for receiving and the oscillator signal as an output signal as a function of the current signal state of the baseband signal applied to the control signal input either only on the first or only at the second signal output, and– a balancing element in the form of a marc hand - balun, whose first input port of the output signal of the three-way switch via the first signal output of the three-way switch is supplied, and whose second input port of the output signal of the three-way switch via the second signal output of the three-way switch can be supplied, and at the output port, depending on the current switching state of the three-way switch as a function of the baseband signal, the oscillator signal in differential form in one of two different phase positions can be picked up.
