In electronic components, 'Double-balanced' is a term mainly used in mixer or multiplier circuits. Double-balanced mixers or multiplier circuits are used to combine or multiply multiple RF (Radio Frequency) signals, and have a feature that minimizes the effects of unnecessary interference or external signals.
Double-balanced mixers and multiplier circuits have the following characteristics:
External Signal Suppressed: Double-balanced circuits use multiple opposite signals to cancel each other out. This suppresses external signals from unnecessarily affecting the output of the mixer or multiplier circuit.
High suppression rate: Because the double-balanced circuit suppresses unnecessary frequency components almost, you can obtain accurate results by maintaining only the desired frequency components.
Image Suppression: Double-balanced circuits have image suppression. Image suppression serves to remove unwanted image frequencies that may occur when the mixer converts the signal to a different frequency.
Low Loss: The double-balanced circuit provides low loss, minimizing the loss of the original RF signal and reducing the multiplication as much as possible.
Double-balanced mixers and multiplier circuits are used primarily in RF and microwave applications, especially in high-frequency applications such as radar, communications systems, radio communications, and satellite communications. These circuits are considered critical components in RF systems that require high performance and accuracy.
