Abstract
This paper presents a feasibility study for a very high data rate receiver operating in the K/Ka-band suitable to future Moon exploration missions. The receiver specifications are outlined starting from the mission scenario and from a careful system analysis. The designed architecture uses a low noise front-end to down-convert the incoming K/Ka-band signal into a 3.7 GHz intermediate frequency (IF). For maximum flexibility, a software defined radio (SDR) is adopted for the I/Q demodulation and for the analog to digital conversion (ADC). The decoding operations and the data interface are carried out by a processor based on field programmable gate array (FPGA) circuits. To experimentally verify the above concepts, a preliminary front-end breadboard is implemented, operating between 27.5 and 30 GHz. The breadboard, which uses components off the shelf (COTS) and evaluation boards (EVBs), is characterized by a 46 dB gain, a 3.4 dB noise figure and a − 37 dBm input-referred 1 dB compression point. Finally, a 40 Msym / s quadrature phase shift keying (QPSK) signal is demodulated by means of a commercially available SDR, demonstrating the above concept. The importance of these results is that they have been obtained exploiting a class of miniaturized and low cost microwave integrated circuits currently available on the market, opening the way to a dense communication infrastructure on cislunar space.
本文针对适用于未来月球探测任务、工作于K/Ka频段的极高数据速率接收机开展了可行性研究。基于任务场景和详尽的系统分析，给出了接收机的指标规范。所设计的架构采用低噪声前端将输入的K/Ka频段信号下变频至 3.7 GHz 中频（IF）。为了获得最大的灵活性，采用软件定义无线电（SDR）实现I/Q解调和模数转换（ADC）。解码操作和数据接口则由基于现场可编程门阵列（FPGA）电路的处理器执行。为了通过实验验证上述方案，研制了一个工作在27.5至30 GHz之间的前端原理样机。该样机采用商用现货（COTS）组件和评估板（EVB），具备 46 dB 的增益、 3.4 dB 的噪声系数以及 − 37 dBm 的输入1 dB压缩点。最后，利用商用SDR解调了 40 Msym / s 的正交相移键控（QPSK）信号，验证了上述构想。这些结果的重要意义在于，它们是利用目前市面上现有的微型化、低成本微波集成电路实现的，为在地月空间构建密集的通信基础设施开辟了道路。
