2. Mechanical Description 2.1. Mechanical Dimensions Dimensions are in mm. The module pins are arranged with a 1mm pitch distance. The module is designed in a symmetric way. Figure 2-1 Module Bottom Dimensions ( Seen from a CAD top perspective ) The module can be mounted to a base board with a soldered RF connection. For this case one or both U.Fl connectors are left unconnected and the RF pads on the bottom side are used to feed an antenna located on the base board. 2.2.
PAGE 8
For all other I/O pads the geometry in below figure should be used. Figure 2-2 Recommended Base Board Layout 2.2.2. Design without RF-Pads For applications where the antenna is implemented on the base PCB, the RF-Pads can be used to connect the RF signals. The pad layout is available in Figure 2-2 Recommended Base Board Layout on page 8. The base board traces shall be designed with a line impedance of 50Ohm.
