RF-BM-4044B2 www.szrfstar.com Ver1.1 - Aug., 2018 4.4 Basic Operation of Hardware Design 1. It is recommended to offer the module with a DC stabilized power supply, a tiny power supply ripple coefficient and the reliable ground. Please pay attention to the correct connection between the positive and negative poles of the power supply. Otherwise, the reverse connection may cause permanent damage to the module; 2. Please ensure the supply voltage is between the recommended values.
RF-BM-4044B2 www.szrfstar.com Ver1.1 - Aug., 2018 Layer, the copper must be spread on the connection part of the top layer and the module, and be close to the digital part of module and routed in the Bottom Layer (all copper is well grounded). 5. Assuming that the module is soldered or placed in the Top Layer, it is also wrong to randomly route the Bottom Layer or other layers, which will affect the spurs and receiving sensitivity of the module to some degrees; 6.
