Get to know something about RF Transformer.


What does an RF Transformer do?An RF transformer is a device that transfers electrical energy from one circuit to another by electromagnetic induction. It can be used for various purposes, such as impedance matching, voltage or current conversion, DC isolation, signal splitting or combining, and int
What is RF coupler and how to choose RF Coupler?


What is RF Coupler?RF and Microwave couplers are passive devices that divert / couple a fraction of the signal from the main transmission line to another coupled transmission line. The signal output at the main port of the transmission line is called the “direct or through” signal and the other tra
How does radio frequency transformer work and how to measure?


RF transformers are widely used in electronic circuits forImpedance matching to achieve maximum power transfer and to suppress undesired signal reflection.C Voltage, current step-up or step-down.C DC isolation between circuits while affording efficient AC transmission.C Interfacing between balanced
