2.5.3 ESD application circuits
The application circuits described in this section are recommended and should be implemented in any
device that integrates a LISA-U2 module, according to the application board classification (see ETSI
EN 301 489-1 [12]), to satisfy the requirements for the ESD immunity test summarized in Table 51.
2.5.3.1 Antenna interface
The ANT pin of LISA-U2 modules provides ESD immunity up to 1000 V (contact and air discharge
according to IEC 61000-4-2): a higher protection level is required if the line is externally accessible on
the device (i.e. the application board where the LISA-U2 series module is mounted).
The following precautions are suggested for satisfying ESD immunity test requirements:
If the device implements an embedded antenna, the device insulating enclosure should provide
protection to direct contact discharge up to ±4 kV and protection to air discharge up to ±8 kV to
the antenna interface
If the device implements an external antenna, the antenna and its connecting cable should provide
a completely insulated enclosure able to provide protection to direct contact discharge up to ±4 kV
and protection to air discharge up to ±8 kV to the whole antenna and cable surfaces
If the device implements an external antenna and the antenna and its connecting cable do not
provide a completely insulated enclosure able to provide protection to direct contact discharge up
to ±4 kV and protection to air discharge up to ±8 kV to the whole antenna and cable surfaces, an
external high pass filter, consisting of a series 15 pF capacitor (Murata GRM1555C1H150JA01) and
a shunt 39 nH coil (Murata LQG15HN39NJ02) should be implemented at the antenna port as
described in Figure 68, as implemented in the EMC / ESD approved reference design of LISA-U2
series modules
☞ Antenna detection functionality is not provided when implementing the high pass filter described
in Figure 68 and Table 53 as the ESD protection for the antenna port of LISA-U2 series modules.

Table 53: Example of parts for the antenna port ESD immunity protection application circuit for LISA-U2 series modules
With LISA-U230 modules, the ANT_DIV pin provides ESD immunity up to ±4 kV for direct Contact
Discharge and up to ±8 kV for Air Discharge: no further precaution to ESD immunity test is needed, as
implemented in the EMC / ESD approved reference design of LISA-U230 modules.
