1.General
M320 is built according to the PCI express mini card specification and is an
integrated solution using the notebook’s antenna system. It is designed as an
add-in option for integrators of notebook computers and is comprised of several
component parts:
HSDPA wireless network adapter which is the wireless enabler and circuitry
integrated onto the Mini Card PCB together with its mechanical RF shielding.
RF connector, which provides physical connectivity M320 and the antenna
which is integrated into the notebook computer’s mechanical housing.
Voltage regulation circuitry, which converts power from the host power supply
to the core regulated voltage for the HSDPA wireless components.
System connector, which provides the data, control, power, status and UICC
interface between the host and the wireless network adapter.
All components except for the antenna connector are covered by EMC shields. All
power and base band communication are located in the edge connector of the
board. The fastening holes in the upper corners are connected to ground.
