Low Noise Block down converter (LNB) for reception of Direct Broadcast Satellite (DBS) signals

摘要

The receiver has a ZF matrix with frequency converter applying a selected output to a preset ZF frequency band. A coupler block concatenates ZF signals from a ZF converter block and outputs switching signal to an output terminal of cascaded satellite receivers. A power supply device and a micro controller device (26) receive the switching signal and output a control signal to the frequency converter for controlling the matrix. Independent claims are also included for the following: (1) a method of designing a direct broadcast satellite system (2) a method of pairing or coupling of satellite receivers and low noise blocks.
