PCMCIA Wireless WAN Package

PCMCIA Wireless WAN Package

      Disclosed is a mechanical package design that houses wireless
cellular.  This package design meets the requirements for products
specified under the Personal Computer Memory Card Industry
Association (PCMCIA) standard 2.0 dated November 1992.  These are
Type III extended adapters.

      The assembly consists of eleven major components as described
below.  A card assembly (1) is packaged which contains radio
frequency (RF) components and digital logic components, a base
antenna connector (2), an auxiliary antenna connector (3), a headset
connector, (4) and the PCMCIA standard 68 pin connector (5).

      A plastic frame (6) acts as the assembly base upon which the
top cover (7) and bottom cover (8) are positioned.  Additional
features in the frame (6) include a 12 position I/O connector (9) and
molded in features (10) to support mating connectors that plug into
the auxiliary connector (3) and headset connector (4).  Springs in
the underside of the top cover provide Electro-Magnetic Compatibility
(EMC) protection for the finished product (springs not shown).  The
covers are assembled using a unique laser welding process.  But this
design features a stitched welding pattern (11) to ease repair
actions on the card assembly (1).

      Once assembled, a specially designed external/pluggible antenna
(12) is assembled to the base antenna connector (2) to complete the
product.
