Communication products or some industrial control products will often encounter impedance requirements. The type of impedance requirements seems to be divided into single-end impedance and differential impedance. In addition, customers generally put forward the requirements of impedance tolerances, such as requiring impedance tolerances /- 10%. As for the role of impedance, it is actually not related to the profession of selling PCB. This problem is best to ask the guest engineers. The purpose of my understanding of impedance should be to avoid changes in signal transmission as well as the right range. for reference only.
Products: Communication (mobile phone, wireless Internet card, base station, 2.4G intercom, etc.. GPS navigation, antenna amplification product, microwave communication module, wireless communication related to all.)
Requirements: Single: single The end impedance and differential impedance
The impedance matching is to minimize the loss in the transmission.
If the guests want to do impedance, they will be explained separately. CAM engineers know.
In addition to the requirements of communication products, there is also a medical product and aerospace products.
Colida is divided into ordinary impedance and differential impedance. Different impedance requirements are strict, which is more difficult than ordinary impedance production.
Iruchers are for the loss of signal transmission-personal understanding
