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:

The upcoming sixth generation (6G) of mobile communication systems is expected to push technological boundaries by enabling ultra-high data rates and extremely low latency. It aims to support a wide range of innovative use cases, typically categorized into four domains: Network-Enabled Robotics and Autonomous Systems, Multisensory Extended Reality, Integrated Sensing and Communications, and Personalized User Experiences. Among the various promising enablers, sub-THz communications have emerged as a technology candidate for the 6G and beyond era, offering the potential for terabit-per-second data rates to meet the extreme performance demands of these applications. To realize this vision, operation in sub-THz frequency bands is part of ongoing research projects.This application note presents a practical approach to generate sub-THz communication signals for 6G based on using DFT-s-OFDM (Discrete Fourier Transform Spread OFDM) modulation. The implementation is realized on a flexible, GUI-controlled testbed built with Rohde & Schwarz instruments, including the SFI100A vector signal generator, FSW signal and spectrum analyzer and external RF frontends.A custom-built graphical user interface (GUI) coordinates all equipment and enables rapid prototyping of communication signal configurations, control of signal generation and measurement automation.This application note serves as a guide for researchers and engineers looking to evaluate or generate future communication signals in the sub-THz domain using commercial measurement equipment.

This application note helps the user to configure a Rohde & Schwarz vector signal generator for LTE FDD repeater conformance testing. It explains step by step how to set up the baseband signal for the various test cases defined in the 3GPP Technical Specification 36.143.The R&S®SMx vector signal generators provide predefined, LTE-conform test models and are therefore ideal for LTE repeater conformance testing. The test cases in TS 36.143 can be set up with a single instrument which provides all necessary test signals including the four specified repeater stimulus signals.

The UWB (Ultra-Wideband) technology is a short range wide-band radio technology specified for device to device communication operating in unlicensed spectrum. It is an RF positioning technology that enables accurate and secure peer-to-peer ranging between mobile devices with robust resistance to interference while consuming very low energy and coexisting well with other radio communication systems. UWB is used for a variety of different applications, such as asset tracking, secure payment, personal tracker, real time location services and keyless access and start of a vehicle etc. According to ABI Research forecasts, there will be well over 1 billion UWB annual device shipments by 2026. Almost every smart phone shipped in 2026 will support UWB services.Talking about testing aspect of a UWB device, in general two test methodologies can be adopted as other wireless products, either the traditional testing mode (so-called conducted test mode) with wired RF connection between the test measurement equipment and device under test (DUT) or over the air (OTA) test mode in an OTA anechoic chamber. Sometimes, it is not always possible or necessary to perform the tests under conducted mode due to the limiting factors, e.g. cost, space, complexity and direct access to the RF connectors of the product. In this case, OTA testing is then becoming a non-evitable approach. Moreover, OTA testing reflects the usage of DUT in a real condition.In this application note, R&S® OTA test solution covering transmitter (Tx), receiver (Rx) and Time of Flight (ToF) testing in Wireless Automated Testing (WMT) environment is described. The measurement results throughout the whole document are based on NXP Trimension™ NCJ29D5 UWB automotive IC.

Distortions caused by components in the RFFE (radio frequency front end) limit the performance and throughput of communications systems. Types of distortions include:▪ AM-AM and AM-PM (complex variations of gain with amplitude)▪ Non-linear frequency response (memory effect)All RFFE components exhibit all of these distortions, only the proportions vary. In this Application Note, illustrative measurements of individual RFFE components, as well as a complete RFFE, will be made. This is followed by the documentation of a more complete analysis, including comparison against theoretical limits, of a linearized commercial SatCom BUC product.
