Data Sheet

The host Main unit is a SPHE8107H, It has 16Mb flash and needs
24.576MHz
crystal
of
reference
frequency.
This
chip
is
responsible
to
control
DSP, Bluetooth, audio system and all the source of
input
Host .For the FCC certification,
TBM-QCC307B
is without shielding cover test,
If the Host
manufacturer adds a shield cover for the whole machine test, it needs to re-evaluate FCC spurious
emission test and make C2PC.
RF Traces for antennas
The figure below shows the general breakout of the module U2:
Figure 1-1
On U2 PCB board,
A band-pass filter Fil1 needs to be inserted between QCC3007 power
amplifier (PA) output and t
he antenna.
This component can be added to provide additional margin
for emissions testing.
The band-pass filter should be located as close to QCC3007 QFN as possible. The
grounding of the filter is critical to guarantee proper attenuation of the filter out of band. The layout
of the RF section in a QCC3007 QFN system can affect overall RF performance. Ground connections
become increasingly critical at RF frequencies. All ground pins should be connected to the main RF
reference ground plane On the QCC3007 QFN only two of the RF grounds are routed to lead frames,
the others are tied to the paddle underneath the die. See
