用于50公斤级超小型深空探测器PROCYON的X波段15瓦级氮化镓(GaN)固态功率放大器(SSPA)首次在深空进行了演示。PROCYON于2014年12月3日发射,作为Hayabusa 2航天器的子有效载荷。GaN SSPA由三级单端放大器组成。最后一级GaN高功率放大器主导了SSPA的特性,在8.4 GHz时实现了55.8%的最大漏极效率。采用该GaN高功率放大器制作的SSPA尺寸为150 × 120 × 62 mm,重量为1.5 kg,并通过空间环境试验验证了其空间适用性。在深空连续运行超过2450小时,GaN SSPA实现了41.7 dBm(14.8 W)的平均输出功率,标准偏差为0.12 dB,最大总效率为35.7%,平均效率为33.8%。据作者所知,这是所有经过验证的X波段机载SSPA的最高效率。
An X-band, 15-W-class gallium nitride (GaN) solid-state power amplifier (SSPA) for the 50-kg-class ultrasmall deep-space probe PROCYON has been demonstrated in deep space for the first time. PROCYON was launched on December 3, 2014, as a subpayload of the Hayabusa 2 spacecraft. The GaN SSPA consists of three-stage, single-end amplifiers. The final-stage GaN high-power amplifier, which dominates the characteristics of the SSPA, achieves a maximum drain efficiency of 55.8% at 8.4 GHz. The fabricated SSPA using this GaN high-power amplifier has dimensions of 150 x 120 x 62 mm and weighs 1.5 kg, and its space applicability was confirmed through space environmental tests. For more than 2450 h of continuous operation in deep space, the GaN SSPA has achieved an average output power of 41.7 dBm (14.8 W), with standard deviation of 0.12 dB, maximum overall efficiency of 35.7%, and average efficiency of 33.8%. To the authors' knowledge, this is the highest efficiency of all proven X-band onboard SSPAs.
