    This paper addresses the problem of switching watts of RF power with less than 0.5 dB insertion (bypassing) a remotely located LNA (low noise loss with a transition time of less than 100 usec. A amplifier) used for Satellite Communications typical satellite terminal installation is as shown in (Satcom) in the band of...

    Fans have long been used to cool electronic components in enclosures. Unfortunately as minia- turization of electronic systems, such as computers and communication equipment, continues the ther- mal problem of getting the heat out of tightly spaced circuit cards. This paper discusses a novel approach to removing heat...

    Interrupt processing in current PC1 systems is host centric. This architecture works well in PC systems that have a single processor or processor card. However, this architecture causes problems in embedded real-time systems, as well as multi- processor systems. This paper describes how to improve interrupt processing...

    This paper describes a method of combining multiple backplanes together to build a system based on these combined backplanes. Combining multiple backplanes together inherently meant that bridge and host cards as well as associated cabling be utilized. This traditional method of interconnect- ing backplanes wastes...

    As the density of cell sites increases, the per- centage of subscribers that can see multiple cell sites increases. A significant blocking rate improvement can be realized if a subscriber is directed to the cell site with the lightest RF traffic load. If the sites have differing numbers of traffic channels, a method...

    In order to eliminate the negative effects of tar- dem vocoding (increased delay and degraded audio), iDEN uses a protocol to bypass the vocoders in the infrastructure so that compressed VSELP audio is passed between the transcoders (XCDR) instead of PCM. The result is that a virtual point-to- point connection between...
