本文提出了一种用于60GHz通信的16元件相控阵发射机,基于SiGe BiCMOS工艺。该发射机在片上进行全特性表征,实现了相移360度范围内输出功率变化控制在+/-1dB以内。通过两个相邻元件同时探测和外部合路,验证了相位扫描性能。
Ping-Yu Chen3, Scott Reynolds1, Jing-Hong Conan Zhan3, Brian Floyd1 The Tx has been fully characterized on-wafer. The output power from an individual element is measured, for CW input, for different phase (and corresponding gain) settings. This experiment is repeated across 7 adjacent elements. The resulting polar plot in Fig. 11.3.3 indicates that the output power variation across 360º of phase and adjacent elements can be limited to +/-1dB. Two adjacent elements are then probed simultaneously and their outputs are summed in an external output combiner. The phase of one element is swept 360º while keeping the other constant and the aggregated output power is measured. This procedure is repeated for 7 different pairs of elements on the right side of the IC and the results are shown in Fig. 11.3.3 (the output power is normalized to the output power from a single element). In all cases the output signals combine with
