Why Waveguide Leakage Occurs and How to Control It

A waveguide that appears mechanically intact can still radiate enough energy to compromise efficiency, disturb nearby electronics, or create an RF safety concern. Understanding why waveguide leakage occurs requires more than looking for a visible gap. Leakage is an...

How to Prevent Waveguide Arcing Failures

Waveguide arcing is rarely an isolated component failure. It is usually the visible result of an electromagnetic field concentration, an unsuitable material condition, a mismatch event, or a process change that allowed local electric-field strength to exceed the...

Microwave Ablation System Design That Performs

A microwave ablation platform can appear straightforward: generate RF power, deliver it through a cable and applicator, and heat targeted tissue. In practice, microwave ablation system design is a tightly coupled electromagnetic, thermal, mechanical, and safety...

Electromagnetic Failure Analysis Services Explained

A receiver that passes bench testing but loses sensitivity inside its enclosure, a microwave applicator that develops a localized hot spot, or an antenna that shifts frequency after production assembly rarely has a single obvious cause. Electromagnetic failure...

Transmission Line Impedance Calculator Guide

A transmission line impedance calculator is useful long before an RF layout reaches fabrication, but only when its output is interpreted as an electromagnetic model rather than a final guarantee. A calculated 50-ohm microstrip trace may be appropriate for an initial...
