摘要
该文主要研制一种基于北斗二代卫星导航系统B3授权频段的小型化射频前端收发模块。该模块采用多层板技术(printed circuit board,PCB),两路接收通道和一路发射通道,通过优化设计,设计小型化的收发模块,模块实际尺寸仅为50mm×15mm×7.5mm。该收发模块在46.52MHz频率和100k Hz频偏下,测试的相位噪声结果为105d Bc/Hz,收发性能符合指标要求。该射频前端收发模块已应用于某测控系统中,并且此模块也可以广泛应用于车载、移动定位等卫星导航通信与测试中。
A miniaturized transceiver module for Compass II satellite navigation system was designed on B3 band. This module, developed by the Printed Circuit Board （PCB） technology, comprises two transceiver module receiving channels and one transmitter rational distribution channel and was optimized into the dimension of 50 mm×15 mm×7.5mm. According to the experiment, the phase noise of the module is 105 dBc/Hz at 46.52MHz-frequency and 100kHz- frequency offset. The module has been applied in a measurement and control system, so it can be widely used in the communication and testing of on-board and mobile navigation and positioning systems.
