4.1.2   Antenna Reference Design 

When use the SU806 series module, it is necessary to connect the antenna pin with the RF connector or 

antenna feed point on the main board via an RF trace. Microstrip trace is recommended for RF trace, with 

insertion loss within 0.2dB and impedance at 50

Ω.A π-type circuit is reserved between the module and 

the  antenna  connector  (or  feed  point)  for  antenna  debugging.  Two  parallel  components  are  directly 

connected across the RF trace and should not pull out a branch, as the figure shows:

Microstrip  trace  is  recommended  for  the  WIFI/BT  RF  route,  with  insertion  loss  within  0.2dB  and 

impedance at 50
