Local oscillator

Summary

• A local oscillator is a device used to generate a signal which is beat against the signal of interest to mix it to a different frequency. The oscillator produces a signal which is injected into the mixer along with the signal from the antenna in order to effectively change the antenna signal by heterodyning with it to produce the sum and difference of that signal one of which will be at the intermediate frequency which can be handled by the IF amplifier.
