2.5.2 ESD immunity test of u-blox LISA-U2 series reference designs
Although Electromagnetic Compatibility (EMC) certification is required for customized devices
integrating
LISA-U2 modules for RED and European Conformance CE mark, EMC certification (including ESD
immunity) has been successfully performed on the LISA-U2 series modules reference designs
according to the CENELEC EN 61000-4-2 [11], ETSI EN 301 489-1 [12], ETSI EN 301 489-52 [13]
European Norms.
The EMC / ESD approved u-blox reference designs consist of a LISA-U2 series module soldered onto
a motherboard which provides the supply interface, SIM card, headset, and communication port. An
external antenna is connected to an SMA connector provided on the motherboard for the main Tx/Rx
antenna. An additional external antenna is connected to an additional SMA connector provided on the
motherboard for the Rx diversity antenna of the LISA-U230 modules.
Since an external antenna is used, the antenna port can be separated from the enclosure port. The
reference design is not enclosed in a box so that the enclosure port is not identified with physical
surfaces. Therefore, some test cases cannot be applied. Only the antenna port is identified as
accessible for direct ESD exposure.
☞ The u-blox LISA-U2 series reference designs implement all the ESD precautions described in
section 2.5.3.
u-blox LISA-U2 series reference designs ESD immunity test results are detailed in Table 52, according
to test requirements stated in CENELEC EN 61000-4-2 [11], EN 301 489-1 [12], EN 301 489-52 [13].
