RF and microwave filter

<p><a href="/facts/Radio_frequency/aWku7h4R">Radio frequency</a> (RF) and <a href="/facts/Microwave/HmVSN31Y">microwave</a> filters represent a class of <a href="/facts/Electronic_filter/ny7k6VxV">electronic filter</a>, designed to operate on signals in the <a href="/facts/Megahertz/6Wshj5qm">megahertz</a> to <a href="/facts/Gigahertz/6Wshj5qm">gigahertz</a> frequency ranges (<a href="/facts/Medium_frequency/E3qnDG7w">medium frequency</a> to <a href="/facts/Extremely_high_frequency/l28Grdmp">extremely high frequency</a>). It is a component that is used in electronic systems to pass or reject specific frequencies and attenuate unwanted signals within the microwave and RF range. This frequency range is the range used by most broadcast radio, television, wireless communication (cellphones, <a href="/facts/Wi-Fi/u94quCsx">Wi-Fi</a>, etc.), and thus most RF and microwave devices will include some kind of filtering on the signals transmitted or received. Such filters are commonly used as building blocks for <a href="/facts/Duplexer/dlvtRRMQ">duplexers</a> and <a href="/facts/Diplexer/KFgUL9AE">diplexers</a> to combine or separate multiple frequency bands.
