Product Description

In the circuit design of the RF antenna interface, in order to ensure the good performance and reliability of the RF signal, the following design principles are recommended in the circuit design:

The impedance simulation calculation tool should be used for accurate 50Q impedance control of the RF signal line.

The GND pin adjacent to the RF pin should not be used as a thermal pad, and should be in full contact with the ground.

The distance between the RF pin and the RF connector should be as short as possible: At the same time, avoid right-angle wiring. The recommended wiring angle is 135 degrees.

When connecting the device package to establish, pay attention to the signal pin to keep a certain distance from the ground.

The ground plane referenced by the RF signal line should be complete: adding a certain amount of ground holes around the signal line and the reference ground can help improve the RF performance

Yes: the distance between the ground hole and the signal line should be at least 2 times the line width (2*W)
