The PCB 120 can be configured to condition signals passing from the PCB coupler 122 to the output pin 124. The PCB 120 can include any type of circuitry 126 to provide filtering and conditioning to the signals passing from the PCB coupler 122 to the output pin 124. For example, the PCB 120 can include one or more low-pass filters, bandpass filters, band reject filters, high-pass filters, amplifiers, diplexers, Multimedia over Coax Alliance (MoCA) filters, and the like. The PCB 120, the PCB coupler 122, and the output pin 124 include an RF signal transmission path through the coupling/filtering member 118 that conductively couples devices and/or cables connected at the input (e.g., coupler 104) and the output (e.g., threads 218) of the isolator 100. In some implementations, the PCB 120 (including the circuitry 126), the PCB coupler 122, and the output pin 124 can be combined into a single assembly.

In some implementations, the isolator 100 includes a coaxial PCB 130. The coaxial PCB 130 can be configured to provide a connection between the body 102 and the filtering/coupling member 118 and the outer shield 106. While coaxial PCB 130 is illustrated as having cylindrical (e.g., annular) shape, the coaxial PCB 130 can be formed using other profiles (e.g., rectangular, triangular, oval, etc.).
