1 Noise and Nonlinear Distortion in Microwave Systems
Noise in Microwave System
Thermal noise is the most basic type of noise, being caused by thermal vibration
of bound charges. It is also known as Johnson or Nyquist noise.
Shot noise is due to random fluctuations of charge carriers in an electron tube or
solid-state device.
Flicker noise occurs in solid-state components and vacuum tubes. Flicker noisepower varies inversely with frequency, and so is often called 1/ fnoise.
Plasma noise is caused by random motion of charges in an ionized gas, such as a
plasma, the ionosphere, or sparking electrical contacts.
Quantum noise results from the quantized nature of charge carriers and photons;
it is often insignificant relative to other noise sources.

signal)
Cross-modulation (modulation transfer from one signal toanother)

Fundamental Trade-off in Receiver
Using one or more IF stages to relax the filter
requirements, but need to deal with images
Using image reject mixers with I&Q LO signals to
eliminate the need of band-pass filters (to enable higher
level of integration)
RF ICs typically employ a combination of simple mixing
with some image filtering and image reject mixing
