MOUNTING

Figure 4-8 illustrates the mounting suggestions for the

BM71BLE01FC2 module. It also shows a connection to

the UFL connector. A low-impedance ground plane will

ensure the best radio performance (best range, low

noise).

The pin_1 (BT_RF) is connected to an external

antenna connector, a PCB trace antenna, or a compo-

nent (ceramic chip) antenna through a host PCB

50 Ohm micro-strip trace. The micro-strip trace can be

extended to include passive parts for antenna attenua-

tion padding, impedance matching, or to provide test

posts. It is recommended that the micro-strip trace be

as short as possible for minimum loss and best imped-

ance matching. If the micro-strip trace is longer, it

should be 50 Ohm controlled impedance.
