Q.Please advise on the actual use of DC feed terminal (DC feed + RF GND or GND). HF-Komponenten und Module >  HF-Komponenten und Module >  Balun A. In a part of RFIC which is used in the wireless communication devices, there are products that require a DC voltage to be applied to the balanced terminal to provide DC power supply voltage. DC feed terminal is basically a terminal for supplying the DC power supply voltage to such RFIC. Conversely, when used in conjunction with RFIC which does not need to apply the DC power supply voltage to the balanced terminal, it is treated usually as GND. product portal Baluns Kontakt  Fragen zu Produkten, Vertrieb oder bei technischen Fragen
