Figure 1 Block diagram of the BFIC chip in BGA package (not to scale). Modern phased array systems utilize beamformer integrated circuits (BFICs), which typically feature multiple parallel paths on the chip, with independent control over gain and phase for each path. A common BFIC configuration connects two or more RF paths to pins located … Read more
011. Research Background In recent years, the number of subsidence and goaf areas formed during underground coal mining has increased significantly, which greatly impacts the safe operation of power lines. Transmission line towers bear the weight of the wires between adjacent towers. If the degree of inclination and the foundation settlement of the power lines … Read more
This design guide discusses how to design RS-485 interface circuits. It covers the necessity of balanced transmission line standards and provides an example of process control design. The article also discusses line loading, signal attenuation, failure protection, and current isolation under separate headings. 1. Why Balanced Transmission Line Standards are Necessary The focus of this … Read more
