|Reciprocal Mixing - how LO phase noise affects selectivity |
|Reciprocal mixing occurs in a super-heterodyne receiver when the noise |
|sidebands of the Local Oscillator mix with strong signals, that are |
|close in frequency to the wanted signal, producing unwanted noise |
|products at the intermediate frequency and degrading the receiver |
|sensitivity. |
|A typical receiver front end down-conversion stage is shown in Figure 2.1|
