Abstract
The invention belongs to the technical field of navigation, and particularly relates to a miniature Beidou/GPS dual-mode radio frequency module. The miniature Beidou/GPS dual-mode radio frequency module comprises the components of a low noise amplifier, a gain amplifier, a filter, a mixer, a power divider and a frequency synthesizer. After an antenna receives BD2 B1 and GPS L1 signals, low noise amplification is performed through the low noise amplifier. Then the BD2 B1 and GPS L1 signals enter the gain amplifier, and the signal gain is amplified. Finally, through frequency selection of the filter, a BD2 B1 radio frequency receiving channel is separated from a GPS L1 radio frequency receiving channel. Each radio frequency signal generates an I signal and a Q signal of each channel through orthogonal frequency mixing with a frequency synthesizing signal. The I signal and the Q signal are transmitted to a base band processing unit and signal processing is performed. The miniature Beidou/GPS dual-mode radio frequency module has functions of reducing the circuit complexity and the cost, effectively improving and enhancing the circuit performance, adopting a pipe core and a miniature and lightweight microwave integrated circuit and multi-chip assembling, and realizing a requirement of ultra-small volume.
