This allows the local oscillator on the LNB to be referenced to an external signal generator; when fed with a 25.78 MHz signal, it’s enough to goose the LNB up to 10,490 MHz — right about the ...

In a superheterodyne radio, a local oscillator is an electronic circuit that generates a frequency based on the desired channel. The output of the oscillator is the channel frequency typically ...

Later, a number of wireless technologies have emerged, not strictly belonging to the class of communication systems. Some examples are wireless local-area networks (WLAN), sensor networks, wireless ...
