摘要：
An X-Band QPSK transmitter designed for data rates up to 150Mbps for small satellites with power,mass and size constraints is described in this paper. A direct modulation method where the baseband data directly modulate the X-band carrier is applied to the development of the X-band transmitter. This method can reduce the complexity and size of the hardware. 14W (41-5 dBm) RF output power of the X-band transmitter at 8.2GHz center frequency is obtained by a solid state power amplifier (SSPA).
