Introduction to Local Oscillators A local oscillator (LO) is a crucial component in the realm of radio frequency communications and electronic systems. Serving as a signal generator, the LO generates a stable frequency signal that mixes with the incoming signal at the receiver. This mixing process is essential to convert the received radio frequency (RF) …
