F.2 Setup

Table 66: RF Path Losses Calibration Setup
Item Description
PLT board The PLT board could either be outside or inside the shielded box, as shown in
Figure 119 , depending on the fixture setup.
DUTs The DUT antennas should point the RF antenna.
PLT to DUT connections The PLT to DUT cable connections should be as short as possible. Also, the cables
should not block the RF path from DUT to the RF antenna.
Shielded box The shielded box must be big enough to fit the PCBA and the fixture and the PLT if it
is inside.
RF cable - PLT to
shielded box.
This type of cable must have good shielding and low attenuation.
Effective shielding must be >60 dB. Check Table 65 for the best proposals.
If multiple production lines are used, RF cable shielding is important to avoid
disturbance from other close by PLTs. However, if other PLTs are far away (>3 m)
other cables can be used.

FLEXIBLE CABLE 2.6/50 S (RG316 - KX22A) P/N: C291 170 007
Keep the length of the DUT to
PLT cables as short as possible
inside the shielded box. These
should not block the RF path
from DUT to the RF antenna.
