RF Ablation Generator Signal Chain: Components That Matter
An RF ablation generator has one job that sounds simple and is anything but: deliver a controlled dose of RF energy into tissue whose electrical properties change by the second. Cardiac ablation, tumor ablation, and pain management systems all depend on a generator...
What Is a Coaxial Switch? Types, Specs, and How to Choose
Every RF and microwave system that has to send one signal down different paths needs a clean way to route it. A coaxial switch does that job. It connects a common port to one of several output ports through a controlled signal path, so a single instrument can reach...
The Wilkinson Power Divider: How It Works and When to Specify One
Split an RF signal two ways with a plain T-junction and you inherit three problems at once. The two outputs leak into each other, the input match falls apart, and reflected energy bounces back toward your source. A Wilkinson power divider clears all three. It splits...
What Is a Directional Coupler? Configurations, Specs, and Use in Defense Subsystem Integration
Defense subcontractors integrating subsystems for a prime program face a recurring question: how do you measure or sample an RF signal without disturbing the path it sits on? Whether you’re integrating a transmit chain, building a test set, or designing a...
