dB 5.Antenna Information 5.1 Antenna Types TYBT4L has an on-board PCB antenna for BLE . 5.2 Antenna Interference Reduction To ensure optimal RF performance, it is recommended that there be a space of at least 15 mm between the module antenna and other metal parts. TYBT4L is attached to the PCB with other components using the SMT. In this case, the routing position and method of the PCB antenna directly affect the RF performance. The following figures show the recommended and not recommended routing positions. As shown in Figure 5.1, if most of the antenna is outside the PCB frame, solutions 1 and 2 are recommended. The antenna is placed outside the PCB frame or the PCB is carved to reserve an area for the antenna. By using these two solutions, the performance of TYBT4L is almost the same as that of the module when being tested independently. If the antenna must be routed on the PCB due to restrictions, solution 3 is recommended. The antenna is placed inside the PCB frame and no copper or wire is routed near the antenna. If this solution is used, the performance is reduced by about 12 dBm. It is not recommended that solution 4 be used, in which the antenna is placed inside the PCB and copper and other wires are routed under the antenna. In this solution, the RF signal has significantly attenuation. 6 Version1.0.0 TYBT4L V1.0.0 UserManual 6.Packaging information and production instruction 6.1 Mechanical Dimensions and Size of the Back Pad Figure 6.1 TYBT4L size diagram 7 Version1.0.0 TYBT4L V1.0.0 UserManual 6.2 Production Instructions Storage conditions of a delivered module are as follows:
