How Do Filters Work?
Jul , 02 2025
What Is an RF Filter? An RF filter is a passive or active component that allows signals within a certain frequency range to pass while attenuating signals outside that range. Filters are essential in both transmit and receive chains to isolate specific frequencies and prevent crosstalk, interference, or signal distortion. Types of Filters by Frequency Selection Depending on the application, filter...

What's the Difference Between Microstrip and Cavity Power Dividers?
Jun , 26 2025
1. What Is a Microstrip Power Divider? A microstrip power divider is fabricated using PCB (printed circuit board) technology. It typically consists of microstrip lines, branch networks, and resistors. Often based on Wilkinson design principles, microstrip dividers offer good impedance matching and moderate port isolation. Key Features of Microstrip Power Dividers: Compact and lightweight — Ideal f...

Yagi Antenna: Key Advantages and Primary Applications
May , 16 2025
Key Advantages of Yagi Antennas: High Gain and Directivity Yagi antennas are highly directional, focusing radio frequency (RF) energy into a narrow beamwidth. This directional radiation pattern allows for significant gain (typically 8–15 dBi), making them ideal for long-distance communication. The focused beam minimizes interference from unwanted directions, improving signal-to-noise ratios. Cost-...
