RF Input Stage Circuit

1. RF LNA design requirements As the first stage of the RF signal transmission link, the low noise amplifier (LNA) has a noise coefficient characteristic that determines the noise performance of the entire RF circuit front end. Therefore, the design of the first stage LNA of the high-performance RF receiving circuit m

      From the typical applications of oscilloscopes in RF testing introduced above, we can see that: due to technological development, the advantages of oscilloscopes in high bandwidth and multiple channels are very suitable for various complex ultra-wideband applications. At the same time, their comprehensive analysi

RF interface, radio frequency interface, is the interface mode currently used by home cable TV. The imaging principle of the RF antenna interface is to mix and encode the video signal and audio signal and then output it, and then perform a series of separation/decoding processes inside the display device to output t

introduction With the continuous expansion of the scale of industrial measurement and control systems and the diversity of data collection, wired networks are greatly restricted due to the high cost of installation boxes and inconvenience in use. Wireless sensor networks have been widely used in the field o
