Rf Mixer Circuits. It is the core process in rf technology and design. Basic passive switching fet rf mixer concept.
It can either modulate or demodulate a signal. Here the input frequency gets converted into different frequency components so as to process the signals more effectively. Mixers are widely used to shift signals from one frequency range to another a process known as heterodyning for convenience in.
And abidi a.
The rf mixer has 3 ports rf if and lo. In this role the drain source resistance behaves as a voltage variable resistor. Here the input frequency gets converted into different frequency components so as to process the signals more effectively. It has three signal connections which are called portsin the language of radio engineers.
