摘要

由于功率和体积的限制，纳米卫星结构的通信能力有限。大多数卫星都有传感器，比如摄像头，图像传输对数据传输速度的要求也更高。在本项目中，为低轨道卫星(700-900公里)设计2.4 GHz (S波段)通信系统。系统包括片上系统发射装置、前置放大器、带通滤波器、功率放大器和微带天线阵列。在FR4上设计了微带天线阵列和射频电路。微带阵列尺寸为92×84mm2，射频电路尺寸为38×53mm2。系统输出功率为35dBm，数据速率为2.4kbaud，但可以增加到卫星的功率能力，以获得更高的数据速率。

Low cost S Band communication system design for nano satellites

Nano satellite structures have limited communication ability due to limited power and size. Most of satellite includes sensors, for instance camera, also image transfer requires more data transfer speed. In this project, 2.4 GHz (S Band) communication system is designed for LEO satellites (700–900 km). System includes system-on-chip transmitter device, preamplifier, band pass filter, power amplifier and microstrip antenna array. Microstrip antenna array and RF circuit is designed on FR4. Microstrip array size is 92×84mm2 and RF circuit size is 38×53mm2. Output power of the system is 35dBm for 2.4kbaud data rate, but it can be increased to power capability of the satellite for more data rate.
