5 RF PCB Design

5.1 Antenna RF Connector

The antenna of the MC610 series modules is led from bonding pads. It is recommended that customers use the U.FL-R-SMT-1 antenna connector and use the matching RF adapter lines. The antenna is a sensitive device and is easily affected by the external environment. For example, the position of the antenna, the occupied space, and the surrounding grounding may affect the performance of the antenna. In addition, the RF cable connected to the antenna and the fixed antenna position will also affect the antenna performance. Figure 4 shows the reference circuit design of the main set antenna. These matches need to be placed close to the antenna:

Figure 4. RF reference circuit design: This diagram illustrates a typical RF matching circuit for the antenna connection. It shows a transmission line (likely 50 Ohm impedance) connecting the module's RF output to an antenna connector. The circuit includes passive components such as capacitors and inductors arranged in a pi or T network to match impedance. The layout emphasizes keeping the RF trace short and ensuring a solid ground plane.

• Ensure that the characteristic impedance of the transmission line is 50 Ω.
• As the antenna line loss is less than 0.3 dB, keep the PCB routes as short as possible.
• PCB LAYOUT avoids passing through holes and overturning layers as much as possible, and also right-angle and acute-angle route.
• There should be a good reference ground around the PCB routes to avoid other signal lines close to the antenna.
• It is recommended to use intact formations as reference ground.
• The ground around the antenna strengthens the connection with the main ground.
