What Is the Input Impedance of a Log Periodic Antenna?
Jul , 12 2025
Log periodic antennas are widely used in RF communication due to their broadband capabilities. One critical aspect of their performance is input impedance, which determines how efficiently the antenna transfers power from the transmission line. Understanding this parameter is essential for engineers and hobbyists working with these antennas. Why Input Impedance Matters The input impedance o...

Understanding Low PIM in RF Passive Components: Why It Matters
Jul , 17 2025
What is PIM and Why "Low" PIM is Critical? PIM stands for Passive Intermodulation, a form of signal distortion that occurs when two or more high-power RF signals mix within a passive component—such as connectors, cables, power splitters, couplers, or antennas—and create unwanted interference at new frequencies. These new frequencies can degrade system performance, reduce data throughput, and affec...
