Note for RF embedded wireless module LAYOUT

RF embedded wireless modules are widely used in mobile phones and remote controls. These products are closely related to our lives. I believe everyone has used them. In the field of electronic design, there is a motherboard inside the consumer products such as mobile phones and remote controls that you often use. Observing the motherboard, you can see a lot of thin copper wires and pieces of copper. These are the physical manifestations of the RF embedded wireless module LAYOUT. Regarding LAYOUT, there are many constraints to restrict the wiring to achieve the desired purpose, so as to ensure the stability of electronic products. Next, let's take a look at the precautions for the LAYOUT of the RF embedded wireless module.

1. The grounding pin of the module should not be too thin or too long. Generally, a large area is used to lay the ground, so as not to affect the output power of the radio frequency.
2. The antenna should be as far away as possible from other components, especially the power supply.
3. The power supply should be a stable power supply without interference. If there is a booster circuit in the circuit, the boosted voltage should be a voltage with a shield, and the farther away from the module, the better.
4. In the LAYOUT high-power module, the GND next to the ANT should not be connected to the ground of the system. If you want to connect an external connection line, just lead a pad out as shown in the picture, and it must be shorter.

The above are the matters needing attention in the LAYOUT of the RF embedded wireless module. These constraints are to ensure the stability of electronic products. Strict compliance can ensure the quality of the products.
