Embodiment Construction

[0015] Example embodiments of the invention relate to transceiver modules with dual printed circuit boards. Some example transceiver modules disclosed herein enable electrical data signals to be transmitted between the transmitter and the transmitter PCB and received even when the generally parallel plane in which the PCB is located deviates from the plane in which the transmitter and receiver are located. Between the receiver and the receiver PCB.

[0016] Various aspects of example embodiments of the present invention will now be described with reference to the drawings. It should be understood that the drawings are diagrammatic and schematic representations of such example embodiments and do not limit the invention, nor are the drawings need to be drawn to scale.

Abstract

Transceiver modules with dual printed circuit boards. In one example embodiment, a transceiver module includes first and second printed circuit boards (PCBs), a transmitter, a receiver, and a flexible circuit. The first PCB is positioned in a first plane and the second PCB is positioned in a second plane. The transmitter and the receiver are both positioned in a third plane that is offset from the first and second planes. The flexible circuit includes conductive traces that allow electrical data signals to pass between the transmitter and the receiver and the first and second PCBs.

Description

Background technique [0001] The transceiver module usually includes a transmitter, a receiver, and a printed circuit board (PCB), which has circuits related to the transmitter and the receiver, such as a driving amplifier circuit. When electrical data signals are transmitted between the host device where the transceiver module is located and the transmitter and receiver, they usually pass through the circuit. [0002] One difficulty of the transceiver module is to find a reliable and cost-saving device for transmitting electrical data signals between the transmitter and receiver and the PCB. In particular, the relatively small size of typical transceiver modules and related space constraints and interfering components may make it difficult to transmit electrical data signals between the transmitter and receiver and the PCB. Summary of the invention [0003] In general, example embodiments of the present invention relate to transceiver modules with dual printed circuit boards. Som...
