Cavity filters use metallic cavities to form resonators, where electromagnetic waves create standing waves at specific frequencies. These filters, including combline and interdigital types, offer high selectivity and performance up to 30GHz. Despite their size, innovative designs can make them comparable to microstrip or ceramic filters.

Lumped element filters are passive filters made with inductors (Ls), capacitors (Cs), and resistors (Rs) to meet specific filtering needs. They use simple L-C resonators to create poles and zeros in the frequency response, allowing tight control over the filter's performance. These filters are compact, customizable, and can withstand harsh conditions. They can be designed as lowpass, highpass, bandpass, or band-reject filters. Their frequency ranges span from 10 MHz to 22 GHz, making them versatile for various applications.

EMI filtering is an essential element of equipment design to meet international legislation such as the EU Directive on EMC or the FCC. Introducing screening measures to cases or cables, for example, may suffice in many instances, but you might need to introduce low-pass filtering for additional protection as well. Here, we will explore EMI filtering and the terminology for designing effective protection.
