Chapter 4 Application Instructions 4.1 Antenna design guide If customers have high requirements for distance, they can use an external antenna, and the IO port for using an external antenna is PIN27 (ANT). The bottom of the module, including the original antenna position, should be completely covered with copper. The following figure shows the circuit from the module ANT pin to the external antenna. The red thick wire should ensure the impedance control of 50Ω.
between plate thickness, line width and line spacing can be referred as following: FR4 double-sided boards recommended value （H=Board thickness，W=Line width，D=Spacing between wiring and copper-clad） H=1.0mm，W=0.8mm，D=0.2mm H=1.0mm，W=1.0mm，D=0.254mm（Recommended） H=1.2mm，W=1.0mm，D=0.2mm（Recommended） H=1.6mm，W=1.0mm，D=0.2mm （Recommended） （Ask Lierda engineer for more design support） 4.2 Notice for base board layout Save enough clearance zone for antenna .
4.3 Notices 1. Power Supply It is suggested supplying power to the module with DC regulated power supply. The ripple of power supply should as small as possible. Usually the ripple is less than 30 mV. Excessive ripple will lead to poor sensitivity and other connection abnormalities.
the land after more than 3 months, and may lead to such problems as false welding and missing welding during the mounting process. In order to ensure the pass rate of reflow, it is suggested picking 10% of products for visual inspection and AOI detection in the first time of mounting, so as to ensure the reasonableness of the furnace temperature, device absorption method and placement method; Operators at all stations must wear the anti-electrostatic gloves during the whole production process; 5.
