    • An apparatus for processing an RF(Radio Frequency) signal for on board equipment is provided to achieve its miniaturization and lightness by integrating an RF receiver, an RF transmitter and a frequency generator into an MMIC(Monolithic Microwave Integrated Circuit) chip. An apparatus for processing an RF(Radio Frequency) signal comprises a transceiving signal separator(200), an RF signal transceiving module(201,202) and a frequency controller(210). The transceiving signal separator separates a first RF signal received through an antenna and a second RF signal which is transmitted through the antenna. The RF signal transceiving module down-converts the first RF signal into a first baseband signal or up-converts a second baseband signal into the second RF signal. The frequency controller is connected to the RF signal transceiving module, generates an up-conversion signal or a down-conversion signal for frequency conversion and inputs the generated signals into the RF signal transceiving module. The RF signal transceiving module is integrated into an MMIC(Monolithic Microwave Integrated Circuit).
    • 提供一种用于处理车载设备的RF(射频)信号的装置,通过将RF接收器,RF发射器和频率发生器集成到MMIC(单片微波集成电路)芯片中来实现其小型化和亮度。 一种用于处理RF(射频)信号的装置,包括收发信号分离器(200),RF信号收发模块(201,202)和频率控制器(210)。 收发信号分离器分离通过天线接收的第一RF信号和通过天线发射的第二RF信号。 RF信号收发模块将第一RF信号下变频为第一基带信号或将第二基带信号上变频为第二RF信号。 频率控制器连接到RF信号收发模块,产生上变频信号或下变频信号进行频率转换,并将生成的信号输入RF信号收发模块。 RF信号收发模块集成到MMIC(单片微波集成电路)中。
