MC60 provides an RF antenna pad for antenna connection. The RF trace in host PCB connected to the
module
’s RF antenna pad should be coplanar waveguide line or microstrip line, whose characteristic
impedance should be close t
o 50Ω. MC60 comes with grounding pads which are next to the antenna pad
in order to give a better grounding. Besides, a π type matching circuit is suggested to be used to adjust
the RF performance.
To minimize the loss on RF trace and RF cable, please pay attention to the design. The following table
shows the requirement on GSM antenna.
