Lecture 15: Introduction to Mixers

Mixers IF RF LO RF IF LO An ideal mixer is usually drawn with a multiplier symbol A real mixer cannot be driven by arbitrary inputs. Instead one port, the “LO” port, is driven by an local oscillator with a fixed amplitude sinusoid. In a down-conversionmixer, the other input port is driven by the “RF” signal, and the output is at a lower IF

Several other examples arise in the chemistry of acids and bases. First, consider the case of a strong acid such as \(HCl\), which dissociates into \(H^+\) and \(Cl^-\). What does the solvation of the excess ...
