Why Is My RF Signal Weak After Adding a Filter?
May , 16 2026
At first glance, adding an RF filter sounds like a simple upgrade. The goal is usually clear: Reduce interference Clean up the signal Improve network stability Protect sensitive RF equipment But in real projects, many engineers and installers run into the same frustrating problem: “The interference is gone, but now the signal is much weaker.” This happens more often than people expect, especially ...

Combiner vs Duplexer: Not the Same Thing — A Complete Engineering Guide
Jul , 28 2026
Combiner and duplexer are not the same thing. A combiner is a device that merges two or more RF signals into a single output path, with all signals flowing in the same direction — primarily used for power combining on the transmit side. A duplexer is a three‑port device that isolates transmit and receive signals, allowing them to share a single antenna, with the two signal paths flowing in opposit...
