What is meant by RF filters and what does it contain?
RF filters are usually discrete components such as capacitors, resistors and inductors which are connected in such a way with certain specific values to create a series, shunt or tank circuit which allow certain frequency ranges to pass through but reject other frequency range signals. For more info any public library in your state/province would had electronic theory books which will have chapters discussing such a topic and would have a glossary of terms.
