SATELLITE APPLICATION NOTES AND WHITE PAPERS

  • Measuring and Monitoring Satellite Signals
    Measuring and Monitoring Satellite Signals

    Measuring and monitoring the signals in satellite communications systems is as complex as the tasks of those involved in operating such systems. Satellite operators are normally interested in ensuring that transponder use corresponds to the criteria agreed with users in terms of quality and scope, which also includes the detection of any interference signals. Teleport operators are concerned with making the best possible use of the resources with the communications systems, particularly the space segment. This Application Note describes example measurement principles that cover the above-mentioned applications and for which the NRA range of spectrum analyzers from Narda is particularly suitable.

  • A New Generation Of Gallium Nitride (GaN) Based Solid State Power Amplifiers For Satellite Communication
    A New Generation Of Gallium Nitride (GaN) Based Solid State Power Amplifiers For Satellite Communication

    The introduction of Gallium Nitride High Electron Mobility Transistors (GaN HEMT) in early 2000 has left an undeniable mark on the entire satellite communication landscape. It is now possible for the first time since the introduction of the Solid State Microwave Technology to design and manufacture Power Amplifiers that exceed by several orders of magnitude the reliability, linearity, power density and energy efficiency of all existing technologies, being GaAs, LDMOS, or TWT. By C. Damian, VP Product Line Management and Business Development, and D. Gelerman, President and CEO, Advantech Wireless Inc.

  • Using The Q/V Band For Satellite Feeder Links
    Using The Q/V Band For Satellite Feeder Links

    Owners of high throughput satellites are increasingly looking for new ways to increase throughput while maintaining or improving the cost per bit. A key limitation of current Ka-band systems is the simultaneous use of Ka-band for both revenue generating user links and backhaul feeder links. The 40 and 50 GHz bands provide opportunity to move commercial high throughput satellite feeder links out of Ka band, enabling full use of the Ka-band for users.

  • Using the IQC5000A and Spectro-X Software for Signal Capture and Analysis: A Satcom Example
    Using the IQC5000A and Spectro-X Software for Signal Capture and Analysis: A Satcom Example

    This application note discusses how a spectrum capture and playback system can be used to predict and measure bandwidth, and its advantages over traditional signal analyzers for the same application.

  • Characterization of Satellite Frequency Up-Converters
    Characterization of Satellite Frequency Up-Converters

    This application note describes methods using an R&S®ZVA network analyzer, one or two R&S®SMB100A signal generators and an R&S®FSW signal analyzer to accurately measure all the key parameters of frequency converters with embedded local oscillator. A commercial satellite up-converter is used as a device under test example.
