| 摘要 |
A coaxial radio frequency (RF) isolator is disclosed. The isolator includes a first connector that conducts an RF signal received from a first device connected to the isolator. The isolator also includes a conductive body including a second connector and a conductive outer shield that form a first internal cavity. The isolator further includes a dielectric sleeve between the outer shield and the conductive body. In addition, the isolator includes a conductive coupling/filtering member inside the outer shield and the dielectric sleeve. The conductive coupling/filtering member has a cylindrical shape forming a second internal cavity. Moreover, the isolator includes a thru-RF signal transmission path through the first internal cavity and the second internal cavity. The thru-RF signal transmission path receives the RF signal from the first device, conditions the RF signal, and outputs the RF signal to a second device. Further, the isolator includes a coaxial coupling element in the first internal cavity and has a cylindrical shape. The coaxial coupling element connects the conductive body, the conductive filtering/coupling member, and the conductive outer shield. Additionally, the isolator includes a magnetic toroid in the first cavity that surrounds the conductive coupling/filtering member. |
