According to Honor officials, the Honor x50 uses an independent 5G RF chip (Skyworks 8226), which provides better 5G network signal and reception performance together with the Qualcomm X50 baseband chip. At the same time, Honor x50 also uses a number of optimization technologies, such as super WiFi, MIMO technology, etc., to further enhance the network connection experience. To sum up, the Honor x50 does have an RF enhancement chip that leads to a more stable and robust network connection.
As far as I know, the Honor X50 doesn't have an RF enhancement chip. The Honor X50 uses a Balong 5000 5G modem chip that supports 5G network connectivity and communication, but does not have RF enhancement.
