Konvertor pro příjem digitálních družicových snímků v pásmu L / L-band frequency converter for reception of the digital meteorological images

Down converter is a mixer which have a three ports. Two ports are refered as input ports and one port is ouput. One input port is connected to a signal which is transmited by meteorological satellites at frequency 1,7 GHz this frequency falls within the L–band. Meteorogical images are trasmited in L-band. The second input port is connected to a local oscillator in this case voltage control oscillator. The output signal includes sum and differential products, for down conversion is logically used differential product. Down conversion is used to convert data that are transmitted at high frequency to lower frequency which can be futher processed and then displayed data on the end device.
