Description
Technical Field
[0001] The utility model relates to the technical field of mixers, in particular to a passive double-balanced mixer. Background Art
[0002] Mixing is the process of converting the signal frequency from one value to another. The circuit with this function is called a mixer. Mixing is essentially the process of linear spectrum shifting. In a superheterodyne receiver, the purpose of mixing is to ensure that the receiver has high sensitivity, sufficient amplification and appropriate passband, while operating stably. The mixing circuit consists of three components: a local oscillator, a nonlinear device, and a bandpass filter.
[0003] However, it still has some disadvantages. For example, when the mixer is working, the mixer chip will generate heat, and without a good cooling process, it is very likely to cause the mixer to malfunction after being used for too long. In addition, the mixer will also generate a certain amount of noise during operation. Especially when multiple groups of mixers are running, the noise may affect people's hearing.
