  • Spread spectrum radio incorporated in a PCMCIA Type II card holder
    Patent number: 5519577
    Abstract: This invention is directed to a PCMCIA Type II memory card holder assembly for a spread spectrum radio communication card that provides radio frequency interference shielding, electrostatic discharge resistance and heat dissipation. The card holder assembly consists of a multilayer circuit board and a card holder. The multilayer circuit board has a ground plane disposed between a plurality of analog circuit layers and a plurality of digital circuit layers. The ground plane is connected by through vias to ground traces on the surfaces of the circuit board. The card holder consists of a card holder frame in which the memory card is slidably and rotatably mounted so that the ground traces continuously contact the frame, and two outer cover plates which are adhered to the opposing surfaces of the card holder frame.
