Radio Frequency (RF
) basics.
This is a simple tutorial to present fundamentals to characterize
radio receiver performance.
Following characteristics of RF are discussed in detail in this section:
† (SNR), Noise Factor (F), Noise Figure (NF) & Cascaded F.
† Third order IM products and Cascade IP3
calculations.
† IP3 (Third Order Intercept) point. Discussions with a plot.
† Radio receiver characterization - Desensitization, Cross-gain
control and noise
(thermal, shot, etc.).
Discuss SNR, Noise Factor and Noise figure next.
