Patent ID: 8279614

Claim:
A modem comprising: electronic components on a circuit board having a first side and an opposite second side, and a metal encapsulation including: a one-piece front frame arranged on the first side of the circuit board, the one-piece front frame including an outer perimeter wall and one or move internal walls within the outer perimeter, a front cover distinct from and removably secured to the front frame, a one-piece back frame arranged on the second side of the circuit board, the one-piece back frame including an outer perimeter wall and one or move internal walls within the outer perimeter, and a back cover distinct from and removably secured to the back frame, wherein the outer perimeter walls and the internal walls of the one-piece front frame and the one-piece back frame define at least three chambers, including: a first chamber that surrounds analogue send and receive components, including a power amplifier arranged on the first side of the circuit board, a second chamber that surrounds analogue-to-digital and digital-to-analogue components, and a third chamber that surrounds a high-frequency digital signal processor, a field programmable gate array, and a DC/DC power supply, and a metal body surrounding, but not contacting, the power amplifier component arranged on the first side of the circuit board, the metal body being distinct from the metal encapsulation and arranged within the first chamber defined by the metal encapsulation.
