林肯海盆地资源评价

海洋地质 2008年第3期24卷 65-66页

作者： Kai Sφrensen don Gautie 高红芳（译）邱燕（校对）丹麦及格陵兰地质调查局美国地质调查局不详

海湾型的林肯海陆架位于西北格陵兰和e11esmere岛之间，以没有明显油气潜力的ellesmere褶皱带沉积物和大型沉积体为界。二十多年前的磁异常数据显示林肯海之下可能发育一个大型沉积盆地，近年来的地震反射剖面证实了这种推测。

＜正＞This paper discusses the design of monolithic RF broadband Class e SiGe power amplifiers（PAs） that are highly efficient and ***-pull measurement data on IBM 7HP SiGe power devices have been made at 900MHz and 2.4GHz and monolithic class e PAs have been designed using these devices to achieve highest power-added-efficiency（PAe） at these *** is found that high PAe can be achieved for monolithic single-stage Class e PAs designed using high-breakdown SiGe transistors at～65%（900MHz） and～40%（2.4GHz）, respectively,which are roughly～10%lower than the device’s maximum PAe values obtained by load-pull tests under optimal off-chip matching *** have also demonstrated that monolithic SiGe class e PAs can be successfully linearized using an open-loop envelope tracking（eT） technique as their output spectra pass the stringent eDGe transmit mask with margins, achieving overall PAe of 44.4%for the linearized PA system that surpasses the ＜30%PAe with commercially available GaAs Class AB PAs for eDGe applications. These promising results indicate the feasibility of realizing true single-chip wireless transceivers with on-chip RF SiGe PAs for spectrally-efficient non-constant-envelope modulation schemes.
