A Triple-Band Transceiver for Formation Flying Satellite Communication with Dual Circular Polarized Wireless Power and LO Transfer

In this paper, we propose a triple-band transceiver that integrates wireless power transmission (WPT) and satellite communications for low earth orbit (LEO) satellite formation flights, utilizing 24 GHz for LO signaling and dual-polarization WPT, eliminating the internal PLL and solar cells thus significantly reducing power consumption and mass. 65 nm CMOS flip chip mounted ICs in a 4×8 phased array evaluation module demonstrated 3.8mW generated power (2x improvement over single polarization) with dual polarization. In satellite communication relay operation, simultaneous 19/29 GHz communications were achieved with 16 APSK modulation and seamless 5 GHz IF conversion. These innovations solve the energy bottleneck and relay operation.
