The Honor 90 is not equipped with an RF signal chip. The Honor 90 uses the Kirin 990 processing chip, but does not contain a separate chip dedicated to RF signal processing. Rf signals play an important role in mobile phones, including wireless communication, data transmission, etc., and usually require specialized chips for processing and optimization. Although the Honor 90 does not have a separate RF signal chip, the Kirin 990 chip has strong performance and comprehensive processing power, which can meet the needs of most users.
The Honor 90 rear camera uses a 200-megapixel main 32-megapixel wide Angle, and a 32-megapixel front single camera. As for whether it comes with an RF signal chip, I'm not sure, because the Honor 90 is a phone, not an RF signal chip. If you need detailed configuration information about Honor 90, you are advised to visit the official website of Honor 90 or contact Huawei, the manufacturer of Honor 90.
