Apparatus and method for forming multiple independent and dynamically adaptable intermediate frequency signals |
摘要 |
A method of separating individual channels from a composite or broadband RF signal that carries the channels on respective frequencies. An RF signal is received from an antenna at a high impedance input port of a plurality of mixers. A local oscillator (LO) signal is received at a high impedance port of the plurality of mixers. The plurality of mixers separately mix the RF signal to produce a plurality of common intermediate frequency (IF) signals. The plurality of common IF signals are output to filters corresponding to the individual isolated channels then processed to derive their information content. |
