    Abstract: The present disclosure relates to reducing unwanted RF noise in a printed circuit board (PCB) containing an RF device. An isolation filter is embedded in a PCB containing an RDF device. By placing the isolation filter as close as possible to the RF device in order to dramatically reduce unwanted RF noise due to unavoidable coupling between Vias and planes in the PCB structure.

    Abstract: A circuit board assembly includes a printed circuit board (PCB), at least two laser diodes, a number of first bonding wires, at least two photo diodes and a number of second bonding wires. The PCB includes a mounting surface, a first connecting pad, and a second connecting pad, both the first connecting pad and the second connecting pad are positioned on the mounting surface. The at least two laser diodes and the driving chip mounted on the first connecting pad. The first bonding wires each electrically connects the laser diodes to the driving chip. The photo diodes and the transimpedance amplifier mounted on the second connecting pad. The second bonding wires each electrically connects the photo diodes to the transimpedance amplifier.
