The satellite receiver supplies the converter (located outside the home together with the antenna) from power. Further nowadays it is necessary to switch the reception between horizontal and vertical to receive the signals with both polarisation directions. Further it is necessary to select which part of the X-band has to be converted.
The horizontal/vertical switching is done by switching the power supply between 13 and 17 Volt. The band switching is normally done by whether or not modulating the power supply voltage with a 22 kHz signal.
This complete power supply voltage (comprising real power supply and switching information) is fed, via the tuner in the satellite receiver (Set Top Box) through the same (coax) cable that transmits the so called HF signal from the converter to the satellite receiver, to the converter.
In known solutions of satellite receiving systems which have to be able to switch the converter between different polarisation's, and frequency bands a power coil is used to AC separate the power supply from the output which contains the 22 kHz signal. Further a power 22 kHz generator is coupled to this power coil. The 13/17 volt switching is normally done with the main power supply. These solutions are as a consequence complex and expensive.
Nowadays the need arose to control more equipment along the same (coax) cable like amplifiers and switchers and to switch between more sub-bands than two.
Therefore the European Telecommunication Satellite Organization has made a standard "Digital Satellite Equipment Control" (DiSEqC), Mar. 22, 1996. DiSEqC is backwards compatible with the known 13/17 Volt and 22 kHz switching. In addition it can transmit commands by means of 22 kHz bursts.
Disadvantages of prior art satellite receiving systems are that these are not able to handle the more sophisticated equipment's and that the known systems further are complex and expensive. 1. Field of the Invention
The present invention generally relates to a high-frequency coupler for deriving a portion of a high-frequency signal such as a microwave signal or a millimeter wave signal from a main transmission line, and more particularly, to a high-frequency coupler constructed with microstrip lines.

 The satellite receiver supplies the converter (located outside the base in concert with the antenna) from power. Further nowadays it is necessary to throw the reception between horizontal and erect to receive the signals with both polarisation management.
