What is balun?


Balun, a three-port broadband RF transmission line transformerBy converting the match input to differential outputto achieve a balanced connection between the transmission line circuit and the unbalanced transmission line circuitMake the system with different impedances or be compatible with differe

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
