What is low noise amplifier?
Aug , 24 2024
Low-noise amplifier/LNA is a special kind of electronic amplifier, which is mainly used to amplify the signal received from the antenna in communication system, so as to facilitate the processing of electronic equipment in the later stage. Because the signal from the antenna is generally very weak, low noise amplifiers are generally located very close to the antenna to reduce the loss of the signa...

How To Test The Power of a Load
May , 21 2025
To test the power of a load, you can follow these steps: Gather Equipment: You'll need a multimeter, wattmeter, or power analyzer, depending on the accuracy required. Connect the Load: Ensure the load (such as a resistor, motor, or appliance) is properly connected to the power source. Measure Voltage: Use the multimeter to measure the voltage across the load. Make sure to set the multimeter to the...

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...

What Does a Mismatched Coupled Port Actually Affect in a Directional Coupler?
Jul , 23 2025
Directional couplers are widely used in RF systems for signal sampling, power monitoring, VSWR detection, and PIM testing. While these components are passive by nature, their performance is highly dependent on how each port is terminated—especially the coupled port. In real-world applications, improper termination of the coupled port—either by leaving it open, using poorly matched devices, or low-...
