A radio frequency integrated circuit( RFIC) for BeiDou is designed and fabricated for reducing the interference of Bluetooth for BeiDou RDSS. The system architecture and high linear circuits are the most important aspects to realize the RFIC. The test results show that, the RFIC works perfectly without any performance drop under the environment of Bluetooth. It's expected that the problem of the interfer-ence of Bluetooth, even 4G signal can be solved, which is a long-standing puzzle, and the application of Beidou can be accelerated.
