With the growing adoption of the Beidou satellite navigation system, the RF chip&nbsp;plays a pivotal role in ensuring high performance and reliability. This article explores the design and implementation of a Beidou RF chip&nbsp;that addresses Bluetooth interference, a significant challenge faced by integrated and miniaturized navigation terminal devices. By mitigating Bluetooth interference, this chip improves the quality of Radio Determination Satellite Service (RDSS) short messages, essential for fields like geological disaster monitoring, hydrological surveys, and ship navigation. I. Interference Background and Technical Challenges Bluetooth devices, operating in the 2.402\u20132.480 GHz&nbsp;frequency band, are positioned just 8 MHz away from the lower limit of the Beidou RDSS receive band.
