웹Chapter 15. RF Balun. 15.1 Introduction. A balun is a transformation block between a single-ended stage and a differential pair. A balun transforming a signal from a single-ended stage to a differential pair splits a single-ended signal into a pair of differential signals with the same magnitude but 180 ° phase difference. It is called splitter as shown in Figure 15.1(a). 웹A Balun is a device designed to connect two circuits by converting or unconverting balanced and unbalanced loads. The characteristics are frequency range, impedance -unbalanced/balanced, phase difference, insertion loss, and return loss. The frequency range is from 10kHz to 23.6GHz with an impedance from 1:1 to 100/100Ohm and a phase difference ...

Baluns are often used to convert a single-ended signal to differential, without adding noise and while maintaining good distortion. A common example of that is in the driver circuit for a high-speed, differential-input analog-to-digital converter (ADC). Have you ever considered using a differential amplifier to replace a balun in ... scottish licensing objectives
