Abstract
A device to measure intermodulation products of a receiver of at least two electromagnetic signals of different frequencies comprises at least two channels for the transmission of the signals of different frequencies and one reflective reception channel connected to an apparatus for the measurement of intermodulation products. The reception channel enables the transfer of signals in a frequency band centered on the reception frequency band of the receiver. A reflective reception multiplexer/demultiplexer with directional filters provides for the interconnection of the two transmission channels of the reflective reception channel of the receiver.
Claims14
A device for the measurement of intermodulation products of a receiver system of at least two transmitted electromagnetic signals of different frequencies said device comprising:
- at least two transmission channels for said transmitted electromagnetic signals, each channel enabling the transfer of one of said signals of different frequencies;
- a reflective reception channel connected to an apparatus for the measurement of intermodulation products, said reception channel enabling the transfer of electromagnetic signals in a frequency band centered on the reception frequency band of said receiver;
- a reflective reception multiplexer/demultiplexer with directional filters, the inputs/outputs of which are respectively connected to said first and second transmission channels, to the reflective reception channel and to said receiver system, said multiplexer/demultiplexer comprising a directional filter associated with each channel, each of said directional filters transmitting at the frequency of the electromagnetic signals transferred by the channel with which it is associated and being reflective at the frequency of the electromagnetic signals of the other channels and of the intermodulation products located outside the reception frequency band.
