SATELLITE APPLICATION NOTES AND WHITE PAPERS

  • VSAT Connecting Your World

    Very-small-aperture terminal (VSAT) is one of a multitude of modern options that provide global data link coverage. The benefits and attraction of VSAT are clear; highly mobile, rapidly deployable, large geographical footprint and no defined infrastructure requirement. Login to learn more about VSAT and what its benefits are to wireless systems.

  • Better Alternative For Measuring Linearity Of GaN Amplifiers

    GaN devices continue to be a key element in many radar, electronic warfare, satellite and terrestrial communication systems. This article will focus on the applications in which amplifier linearity is the critical attribute.

  • Performance Of A High Efficiency, Ka-Band, GaN-on-SiC MMIC With Low Compression

    The high-power density and high breakdown voltage of GaN-on-SiC make it of particular interest for power amplifiers. This white paper details the design and performance of 28 V, 3-stange, Ka-band, Gan-on-SiC, power amplifier MMIC with high efficiency and low gain.

  • Implementation Margin Of A Satellite Communication System

    To find the implementation margin of a satellite communication system, an EbNo generator can be used to carry out an IF loopback test of the modem to find bit error rate (BER) values at different Eb/No ratios. A plot of these values can be compared with the theoretical curve for the digital modulation scheme.

  • NPR Measurements On Satellite Signals

    Noise-Power-Ratio (NPR) measurements are used to characterize the performance of power amplifiers for satellites or other multi-channel communication systems. This application note covers information on how to perform NPR measurements with spectrum analyzers, and how the R&S®FSW spectrum and signal analyzer offers an automated function for NPR measurements.

SATELLITE PRODUCTS

Qorvo offers the CMD240C4 wideband GaAs MMIC distributed amplifier housed in a leadless 4x4 mm surface mount package. The amplifier operates from DC to 22 GHz and is ideal for radar, space, satcom, test and measurement, and electronic warfare applications.

L3 Narda-MITEQ’s SBL series of fiber optic link components are designed to supply high performance, “plug & play” fiber optic link components for linear and some digital applications. The SBT-4000 fiber optic transmitter and the SBR-4000 fiber optic receiver can transport RF signals within the frequency range of 10 MHz to 4 GHz, over tens of kilometers of standard single mode optical fiber.

Avcom offers the new EVO-RSA-6070A as part of the EVO Series of rack mount analyzers. This extended frequency remote spectrum analyzer is designed to operate in the 70 MHz – 6 GHz frequency range. This SDR-style technology analyzer with a wide bandwidth receiver, employing FPGA, DSP, and high-performance processors. The analyzer is based on a hybrid swept-FFT technology which provides extended frequency range and higher resolution.

AtlanTecRF offers a new compact, lightweight and high efficiency drone payload satellite simulators with operation in either the Ka-band (30 GHz uplink and 20 GHz downlink) or Ku-band (14 GHz uplink and 11 GHz downlink) with options for both circular and linear polarization. This Drone Satellite Series (DSS) offers battery powered, cable-less RF test solutions for military and other Unmanned Airborne Vehicle (UAV) applications.

The JFW Model 50MS-367 is a 4 X 4 blocking matrix switch designed to operate in the DC-40 GHz frequency range, and is ideally suited for SATCOM and wireless 5G signal routing applications. 

Horizon Technologies offers the new FlyingFish™ Airborne Satellite Monitoring System (ASMS) designed to enable international government bodies to passively monitor satellite communications from airborne monitoring platforms. This lightweight, cost-effective system can monitor Thuraya, and Isat-Pro networks, and can detect and intercept terminal and call activity such as voice, fax, data, and SMS within radio line-of-site.

The LSS series of Ka-band satellite simulators are designed to enable completely portable RF mobile satellite communications systems testing without the need for cabling. They are equipped with dual polarized horn antennas in both the uplink and downlink bands. For each frequency conversion, a separate attenuator provides adjustments of signal levels in order to accommodate receiver sensitivity and range distance.

The new quad-band satellite simulator from Tampa Microwave is designed as a compact, easy to use training and evaluation tool for satellite earth terminal applications. This device simulates C, X, and Ka-bands simultaneously at over 300 ft. of operation.
