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...

Millimeter Wave Packaging Guide for RF Teams

At 28 GHz, a bond wire that looked electrically insignificant in a lower-frequency design can become a meaningful inductive discontinuity. At 77 GHz and above, a few mils of placement error, excess dielectric thickness, cavity resonance, or an uncontrolled ground...

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...

RF Safety Training for Engineering Teams

A high-power amplifier is not inherently dangerous because of its nameplate rating. Risk arises when radiated, coupled, or leaking electromagnetic energy reaches people under actual operating conditions. A test setup may be safe at the instrument panel yet create an...

Patent Technical Support for RF and Microwave IP

A disputed phrase such as “impedance matching network,” “electromagnetic coupling,” or “configured to resonate” can determine the scope of a patent matter. In RF and microwave technologies, patent technical support must go beyond a surface-level comparison of drawings...
