We present a fully operational 77 GHz SiGe mixer assembled in a chip-scale embedded Wafer Level BGA (eWLB) package. This innovative package has a footprint with a standard pad pitch of 0.5 mm and a standard package height of 0.4 mm. The results demonstrate an excellent potential of the eWLB package concept for mm-wave applications. The measured gain of the packaged mixer is in best case only 1 dB smaller than measured on-wafer. Further, we analyze the transition from the printed circuit board (PCB) to the chip in package. We compare the results of our analysis with the measured performance of the packaged mixers. We achieve a good agreement between simulations and measurements. Finally, we discuss the methods for improving the electrical performance of the packages assembled on the PCB. IntroductionWith increasing performance of Si-based front-end technologies, wireless systems at mm-wave frequencies become more and more important [1-3]. Adaptive Cruise Control (ACC) radar system at 77 GHz [4,5], point-to-point radio link at 60 GHz or high resolution radio imaging at 94 and 140 GHz [6] are only a few examples of applications observed for upcoming markets. With frequencies raising beyond 10 GHz the impact of packages on the overall electrical performance of the integrated circuits (IC) becomes increasingly important. Therefore, the availability of high performance packages for monolithic microwave integrated circuit (MMIC) is crucial for the continued development of commercial mm-wave applications.In literature, some approaches for mm-wave package solutions have been published e.g. based on Rogers 4350 substrate surface mount-type (SMT) package for 1-40 GHz applications [7], or 77 GHz ceramic SMT package using an electromagnetic coupling as second-level interconnects [8]. However, since they use standard laminate-based integration techniques, the resulting package is rather bulky and costly. Another candidate for high frequency applications is the thin small leadless package (TSLP) [9,10]. In [11], an 80 GHz VCO successfully integrated in the TSLP has been reported.

Microwave generation has been extensively investigated due to their application in telecommunication and promising use in emerging technologies like internet‐of‐things (IoT) devices. The current approaches to generate microwave using voltage‐controlled oscillators have the problem of high power consumption. Spin torque oscillators have been investigated as an alternative, but they suffer from a weak output signal. Hence, there is a need for an alternative approach which overcomes these issues. Here a new approach is reported, which relies on the motion of domain walls to generate microwave with strong signal and lower power consumption. In this study, a magnetic nanowire with a sequence of oppositely magnetized domains in one half of the nanowire is simulated. The domain walls are moved by applying spin–orbit torque to the nanowire. It is proposed to generate microwave by detecting the changes in magnetization value using a magnetic tunnel junction in real application. The oscillating frequency of magnetization is found to be in GHz. It is demonstrated that the frequency can be tuned by varying the applied current density. The outcome of this work promises the application of the reported method to generate microwave in nanoscale devices of the future.
