App note: How RF transformers work and how they are measured

Application note from Mini-Circuits about transformers, this time the RF transformers. Link here (PDF) RF transformers are widely used in electronic circuits for * Impedance matching to achieve maximum power transfer and to suppress undesired signal reflection. * Voltage, current step-up or step-down. * DC isolation between circuits while affording efficient AC transmission. * Interfacing […]

App note: Transformers

App note from Mini-Circuits on transformer types and some basics of them. Link here (PDF) The purpose of this application note is to describe the fundamentals of RF and microwave transformers and to provide guidelines to users in selecting proper transformer to suit their applications. It is limited to core-and-wire and LTCC transformers.
