  1. 1.
    This publication describes a dual mode K-Band antenna for use on spacecraft communications links. A constellation of Low Earth Orbit (LEO) satel- lites is being developed for the Iridium7M'SM program which uses communication links between satellites (SV) and Earth stations in the 30/20 GHz commu- nications band. Each...

  4. 4.
    This paper describes a novel method of approach- ing the problem of bond wire interfaces for transi- tions to microwave and millimeter-wave hardware. In general, Monolithic Microwave Integrated Cir- cuits (MMICs), and Multi-Chip Modules (MCMs), make their electrical connections using wire bonds. However, these wire...

    Physical compartmentalization of electronic cir- cuitry prevents signal cross-talk and satisfies other EMI/isolation requirements. Relatively thick, custom- machined plates (often aluminum or alloys thereof) are usefully employed therefor when small quanti- ties (e.g., < 100 pieces) are needed and when the costs of...

  8. 8.
    This publication describes the determination of changes in the relative phase ofa transmitting source by utilizing the receivers optimum sampling point From a digital phase detector/integrator as phase information. This system is particularly useful in a burst mode satellite to satellite link where range rate...

    The Motorola Modular Microcontroller Family MCUs support a Low Power STOP (LPSTOP) mode. In Low Power STOP mode the MCU goes to it's lowest power consumption state under the CPU con- trol. In this LPSTOP mode, the external bus is not used by the MCU since the CPU is not available to run external bus cycles. To reduce...

    In the Motorola Modular Microcontroller Fam- ily, as in the 68000 family, the hmction code signals FC[2:0] are basically an extension of the address bus, providing multiple address spaces. These spaces are designated as either user or supervisor, and program or data spaces. One address space has been desig- nated as...
