  • Patent number: 6329949
    Abstract: A transceiver (100) comprises a stacked metal laminate assembly of a plurality of layers (104-112) inside an enclosure (102). A first layer (104) forms an antenna. A second layer (106) forms a ground plane for the antenna. A third layer (108) forms “front-end” filters (duplexer). A fourth layer (110) together with the second layer forms an electromagnetic isolation enclosure for the filters. A fifth layer (112) comprises a PC board with electronic circuits of the transceiver mounted thereon, and is both mounted to and electronically shielded by the fourth layer. Each of the first through fourth layers is preferably made from a single metal layer, such as a sheet of metal, by stamping. Each of the first through fourth layers is either bent along its periphery into a substantially “cake-pan” shape, or is flat and has a separate side wall (130) attached thereto.
