➢
The GND pin adjacent to the RF pin should not have thermal welding plate 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
the right-angle route. The recommended route angle is 135 degrees.
➢
When connecting the device package, it should be noted that the signal pin must be kept away from the
ground.
➢
The reference ground plane of the RF signal trace should be complete; adding a certain amount of ground
holes around the signal and the reference ground can help improve the RF performance; the distance between
the ground hole and the signal trace should be at least 2 times the line width (2*W).
