摘要： According to the present invention a five-port junction device for processing (down-conversion etc.) of RF-signals is proposed. The device comprises one passive four-port means (1) being connected with a passive three-port means (2) by a phase-shifting element (3). The passive four-port means (1) comprises a port (4) for the input of a first RF-signal and two output ports. The passive three-port means (2) comprises a second port (4) for the input of a second RF-signal and one output port. The output ports respectively provide output signals being linear combinations of the first and the second RF input signal. Power sensors P 1 , P 2 , P 3 are provided to detect the respective power levels of the output signals.
Respectively one power sensor can be connected to one of said output ports and a signal processing unit (26) is provided to calculate the complex ratio of the first and second input RF-signals on the basis of the power level values detected and output by the power sensors P 1 , P 2 , P 3 .

摘要： The present invention relates to a method and a device for the I/Q demodulation of modulated RF signals. The I/Q demodulator (60) has a first input for the RF signal (61) to be demodulated and a second input for a RF signal (62) originating from a local oscillator (20). The demodulator (60) combines the two RF signals (61,62) to generate three output signals supplied to three power detectors. In a combination unit (70) the three power signals of the power detectors are merged in two signal branches wherein after passing an A/D converting (72) and digital processing unit (73) one signal is the I component and the other one is the Q component of the received modulated RF signal (61).

摘要： A demodulator for modulated RF signals comprises a passive four port structure (1). The four port structure (1) has a first input (3) for supplying a modulated RF signal to be demodulated. A second input (2) is supplied with a RF signal from a local oscillator (21). Two output terminals are connected to power sensors (4, 5). The RF signal from the local oscillator (21) is supplied to the second input (3) of the four port structure (1) without being RF switched by RF switch.
The demodulator is particularly useful for modulation schemes with a finite number of magnitude states (nQAM modulation).

摘要： To provide a microwave finline configuration which has no equivalent in unilateral finline, two different finline circuits extend in a common length of waveguide (1, 2), suitably on opposite major surfaces of a common dielectric substrate (3). A pair of Doppler mixers may have identical finline circuit patterns formed by sheet conductors (4 and 5, 6 and 7) with identical mixer diodes (10, 11) connected across their respective fin transmission lines, the finline circuits differing in the longitudinal positions of the diodes (10, 11), which positions are such as to provide respective beat-frequency output signals, via low-pass filters (12, 13), in phase quadrature.

摘要： A five/six-port circuit (100, 200) comprising a waveguide (105, 605?) on a main surface (113) of a substrate (112). The hollow waveguide (105, 605) comprises probes (106, 107, 108) arranged longitudinally inside the hollow waveguide arranged to contact the input port of one of three power detectors (120, 125, 130), whose output ports are arranged to contact the input port of one power detector. The output ports of the power detectors contact the conductor of an open waveguide (105) which extends in parallel to the hollow waveguide. The probes are equidistantly spaced with a distance of L. The circuit also comprises three LP filters (150, 155, 160), each of which is connected to the conductor (105) of the open waveguide at a position which corresponds to the position of one of the power detectors.
