一种新的17瓦，8.4 GHz，固态功率放大器(SSPA)已经被开发出来，用于喷气推进实验室的火星探测车任务。SSPA由功率放大器微波模块和高效DC-DC功率转换器模块组成，集成在一个紧凑的封装中，可以安装在航天器天线附近，以最大限度地减少下行链路传输损耗。SSPA的额定输出功率为17瓦，输入直流功率为59瓦，额定输入信号为+1 dBm。该装置有资格在真空或火星大气中-40/spl deg/C至+70/spl deg/C的温度范围内运行。
A new 17-Watt, 8.4 GHz, solid state power amplifier (SSPA) has been developed for the Jet Propulsion Laboratory's Mars Exploration Rover mission. The SSPA consists of a power amplifier microwave module and a highly efficient DC-DC power converter module integrated into a compact package that can be installed near the spacecraft antenna to minimize downlink transmission loss. The SSPA output power is 17 Watts nominal with an input DC power of 59 Watts and nominal input signal of +1 dBm. The unit is qualified to operate over a temperature range of -40/spl deg/C to +70/spl deg/C in vacuum or Martian atmosphere.
