FPGA logic design has become a highly specialized hardware design field, which requires designers to master design tools, have a deep understanding of the internal structure of FPGAs, and flexibly use
[size=4]Introduction to Passive Intermodulation[/size] [size=4] The problem of passive intermodulation interference has a long history in the communications industry and the RF connector industry. In
As we all know, the circulator has a unidirectional transmission characteristic. The incident signal can pass smoothly (insertion loss is less than 1db ), and the reflected signal cannot pass because
