Webbthe local oscillator exhibits finite phase noise. When the two signals are mixed with the LO output, the downconverted band consists of two overlapping spectra, with the wanted … WebbReciprocal mixing may cause the receiver noise floor to increase when strong signals are near the receiver’s tuned frequency; this limits the ability to recover weak signals. All of …
WebbReciprocal mixing [phase noise]. The local oscillator that feeds a mixer in a receiver always has a certain bandwidth because of the phase noise that arises in each oscillator. This … WebbReciprocal Mixing. Reciprocal mixing occurs when noise sidebands from the local oscillator (LO) signal in a superheterodyne receiver mix with a strong undesired signal that is close to the desired signal.
