description The utility model discloses a full frequency band simultaneous output low noise frequency demultiplier. A vertical signal in satellite signals is demultiplied by a vertical frequency demultiplying circuit into a low frequency band vertical signal and a high frequency band vertical signal, and a horizontal signal in the satellite signals is demultiplied by a horizontal frequency demultiplying circuit into a low frequency band horizontal signal and a high frequency band horizontal signal. The low frequency band vertical signal, the high frequency band vertical signal, the low frequency band horizontal signal and the high frequency band horizontal signal are respectively converted by four frequency band converting circuits into four signals which have nonoverlapping frequency bands, and finally a multiplexer is used for simultaneously outputting the four nonoverlapping signals.
