| The present state of oversea millimeter wave inter-satellite link is demonstrated all-around in this paper. The calculation of link is done also as an important point. The feasibility study about these various inter-satellite links are operated, and at the same time the corresponding technical parameters are got from the study. Then the several parts of the system, just as antenna, transmitter, receiver and base-band processing are researched one by one, especially, the key technologies of the system, as the TDAS antenna of GEO-LEO link, mixer, local oscillator, demodulation and inspect technology, and benchmark demodulation technology are analyzed detailed. Five key devices are studied, which are millimeter wave low power amplifier, millimeter wave low noise figure amplifier, millimeter-wave 0/ phase modulator, 14 to 56GHz millimeter wave quadruples... |
