Abstract
A transceiver module including an adaptor and a PCB is provided. The PCB, connected with the adaptor, has a first signal layer, a second signal layer and a singular ground layer wherein the singular ground layer is set between the first signal layer and the second signal layer. The first signal layer includes a first transmitter circuit region and a first receiver circuit region. The second signal layer includes a second transmitter circuit region and a second receiver circuit region. The singular ground layer includes a ground portion of a third receiver circuit electrically connected with the ground signals of the first and the second receiver circuit region. Beside, the projection area of the singular ground layer onto the first signal layer substantially covers the first transmitter the first receiver circuit region. The ground portion of the third receiver circuit is electrically connected with a ground of the adaptor.
