  • Be ahead in 5G Turn visions into reality - Brochure

    Up to now, concrete and confined use cases such as mobile voice for 2G and mobile data for 4G dominated the definition of cellular technologies. The next generation of mobile networks, 5G, introduces a paradigm change ...

  • Generating Multiple Phase Coherent Signals – Aligned in Phase and Time

    Rohde & Schwarz signal generators present a compact easy-to-use solution for generating phase coherent signals. Different generator models can be coupled to optimally fit user requirements in terms of number of phase coherent channels and RF frequency range.This application note explains how to generate phase coherent signals, details what to consider and how to best calibrate the relative phases and timing between the individual channels. This document also presents various measurements of the phase stability over time for different RF frequencies.

  • High-Speed Remote Control of R&S SGMA RF Sources

    This application note describes how to remotely control the R&S SGMA RF sources SGT100A and SGS100A with a special focus on their high-speed remote control capabilities via LAN based FAST Socket or FAST PCI Express (PCIe) connections which allow round trip setting times of only 100μs.It therefore provides a brief introduction into the general remote control capabilities, explains the interaction of the different SW protocol layers and drivers, and in detail describes how to establish a high-speed remote control connection. Finally, a comparison of the measured setting time performance of the different remote control approaches is provided.

  • 5G Waveform Candidates

    Enhanced Mobile Broadband, Massive Machine Type Communication, Ultra-reliable and low latency communication have been identified as the requirements to be supported by the 5thGeneration of Mobile Communication, short 5G. 5G is extensively discussed in the wireless industry. A lot of research and pre-development is being conducted worldwide, including an analysis of the waveforms and access principles that are the basis for current LTE and LTE-Advanced networks.In this application note we discuss potential 5G waveform candidates, list their advantages and disadvantages and compare them to Orthogonal Frequency Division Multiplexing (OFDM), which is used in LTE/LTE-Advanced.

  • Millimeter-Wave Beamforming: Antenna Array Design Choices & Characterization

    Millimeter-wave bands are of increasing interest for the satellite industry and potential 5G bands.Antennas for 5G applications make use of these high frequencies to incorporate a large count of radiating elements. These antenna arrays are essential for beamforming operations that play an important part in such next generation networks.This white paper introduces some of the fundamental theory behind beamforming antennas. In addition to these basic concepts, calculation methods for radiation patterns and a number of real world measurement results for linear arrays are shown.

  • Linearization of RF Frontends

    Widespread adoption of higher order modulation schemes, larger signal bandwidths and higher operating frequencies, to enable higher data throughput in communication links like 5G, places increasingly tough demands on the frontend. Signal fidelity is often enhanced with linearization.The greater number of RF chains and signal bandwidth in 5G Frontends mean that DPD (Digital Pre-Distortion) may no longer be the default linearization choice; 5G Frontends will be completely different from their 4G predecessors.The key metrics of Efficiency, Linearity, Bandwidth and Output Power remain, as does the question of how to optimally create the signal with just enough fidelity and power, with a minimum of wasted power. The solution set to that question, however, has never been greater.Amongst other topics, this White Paper, (i) proposes a classification of Linearization schemes, (ii) introduces the hard limiter, (iii) illustrates linearization of an exemplary mmWave PA using non-DPD techniques, and (iv) introduces a class of linearized transmitters that create their signal and linearity from efficiently generated components.

  • Doherty, Balanced, Push-Pull & Spatial Amplifier Performance Enhancement

    The Doherty Amplifier continues to be rolled out in an increasing number of TxFE (Transmit Frontend) applications, as the quasi-linear amplifier architecture of choice.The advent of 5G, with its inevitable microwave or millimeter wave air interface, increase the design challenges associated with its construction; not least of all because of the potential for increased dispersion in the constituent amplifiers and combiners.This application note describes a measurement-based development methodology by which the Doherty Amplifier may be enhanced, increasing performance and/or performance bandwidth. This methodology is supported with a working example.The methodology may also be extended to balanced, spatially combined and anti-phase (so called "pushpull" or "differential") amplifiers, the latter often itself nested in Doherty configurations.The R&S®Quickstep sequencing software may be downloaded from:https://www.rohde-schwarz.com/software/quickstep/
