RF Mixers

RF (radio frequency) mixers are electronic circuits that are used to combine two RF signals to produce a new signal at the sum and difference frequencies of the original signals. These mixers are used in a variety of applications, including wireless communication, radio and television broadcasting, and radar systems. RF mixers may be passive or active, depending on the design of the circuit. Passive mixers are simpler and less expensive, but have lower performance and may not be able to handle high-power signals. Active mixers typically use an amplifier to boost the signals, improving performance and allowing them to handle higher-power signals. RF mixers are an essential component of many electronic systems, providing a means of combining RF signals to produce new signals at different frequencies.
