Abstract in simplified Chinese:一种场板MESFET,包括复数个FET组件。每一个FET组件包括掺杂平面信道及耦合于前述信道各端之源极与汲极。闸极导体延伸至位于前述源极与汲极间位置处之前述信道的一部分上方,与前述汲极保持第一预定距离。场板与前述闸极导体相连且朝前述汲极延伸第二预定距离,除与闸极导体链接外,前述场板借由介电材料与前述信道绝缘。
Abstract in simplified Chinese:在HBT数组中之HBT架构成非线性排列,亦即交错式(staggered)排列,因而降低该数组中之相邻HBT间之热耦合影响以及可以不受线性HBT数组所需之最小集极-集极间距设计守则之影响。使用此种非线性架构,相邻HBT彼此间不对齐。在一较佳实施例中,该数组中之相邻HBT架构成边角对边角排列,以及在一更佳实施例中,相邻HBT之集极系对准或共模(common),亦即一HBT之集极共享一相邻HBT之集极。在一最佳实施例中,该些HBT镇流成射极-镇流/基极-镇流样态(称为”混合式镇流(mixedballasting)”或”双镇流(dual-ballasting)”)。

Abstract:
A method and apparatus for signal power ramp-up in a communication transmission. Payload data is identified (210, 410) for transmission. A power reference signal is determined (220, 420) for transmission prior to the payload data. The power reference signal and the payload data are combined (230, 430) to form a data burst for transmission. The combined data burst is transmitted (240, 450) as, wherein the power reference signal is transmitted prior to the payload data within the data burst. A feedback signal is provided (250, 460) based on the power reference signal portion of the transmitted data burst, and a pre-distortion signal is calibrated (260, 470) based on the feedback signal.
Abstract:
A transcoder architecture and method for transcoding in land mobile radio (LMR) systems are provided. The LMR system (20) includes a first communication site configured to communicate using a first LMR communication protocol and a second communication site configured to communicate using a second LMR communication protocol. The LMR system further includes a transcoder (28) configured to receive LMR content from the first communication site communicated using the first LMR communication protocol and digitally convert the LMR content to the second LMR communication protocol to be communicated to the second communication site.
Abstract:
A multiple protocol land mobile radio (LMR) and a method for communicating LMR content are provided. The method includes communicating the LMR content using a plurality of LMR transport protocols within a single LMR network. The method further includes encapsulating the LMR content based on an LMR application layer protocol for a portion of the single LMR network through which the LMR content is to be communicated.
