RF and Microwave
Design: Multimode, multiband transceiver technology delivers LTE Success of LTE technology is tied to an ecosystem development that must take place at the same pace—or faster—than that of the infrastructure implementation. View the full article HERE.
A short history of spread spectrum What do the actress, pianist, German, and inventor have in common? It sounds like the start to a bad joke but the answer is frequency hopping spread spectrum technology View the full article HERE.
Testing modern MIMO Wi-Fi and LTE radios Testing MIMO radios requires new-generation over-the-air (OTA) technology. View the full article HERE.
Analog design in the 21st century: challenges, tools, and IC advances Let’s take a look into the analog sector’s crystal ball and see what’s coming to the rescue of analog designers to help them in the scope of variables they must manage, the extreme sensitivities to circuit constraints, and the quality of results necessary to make analog design as much of an art form as it is a science View the full article HERE.
RF in Action: Ultra-high-performance design In this RF in Action piece, we look at how Spectrum Integrity streamlined its design process using Altium Designer. View the full article HERE.
Radar Essentials Promising to cover the essentials in 128 pages, this spiral bound book lists principles, data, tables, and equations commonly used by radar and aerospace system designers. View the full article HERE.
Ultra-low-power wireless makes inroads into many applications Once the insignificant step children of the wireless world, lower-power wireless technologies are hot, and they are making inroads into many new applications. View the full article HERE.
Hands on RF: Handle multiple waveforms in a software-defined radio platform This paper steps through a software defined radio project that used the secure Xilinx® Zynq™-7000 Extensible Processing Platform (EPP). View the full article HERE.
Understand and characterize envelope-tracking power amplifiers In contrast to fixed supply PAs, the performance of an ET PA is not ‘self contained’ and requires substantially more data to be gathered to predict system performance. View the full article HERE.
Optimize SDR performance Hands-on example using AWR Visual System Simulator: This article explains the attributes of SDR, the design challenges, and it includes hands-on examples of how AWR’s Visual System Simulator (VSS) software for system simulation of RF end-to-end architecture design can be used to address these challenges.

Backhaul for small cells: A 1.5 billion dollar market opportunity In the strategic plans of leading major network operators, handling dense data traffic loads has become more critical than voice coverage in every corner. View the full article HERE.
Test MIMO over-the-air with a two-stage method One way to accurately predict the real-world performance of a mobile device is through the use of over-the air (OTA) testing, or in the case of LTE, Multiple-Input Multiple-Output (MIMO) OTA testing. View the full article HERE.
Ham radio in the 21st century Ham radio today differs greatly from that of past years, but it still offers a fascinating way to explore electronics. Here’s a look at how it has changed and what it has to offer both old hands and newcomers alike. View the full article HERE.
Achieving the lowest power in wireless sensor networks Low-power circuit design: Energy harvesting and SOC designs are key to reducing power consumption in autonomous wireless sensor networks. View the full article HERE.
What's up with Linear Technology? How have things changed at Linear over the years? Bob Dobkin, VP Engineering, Chief Technical Officer, and Linear co-founder was gracious enough to sit down with the RF & Microwave Designline and tell us about it. View the full article HERE.
Hunting noise sources in wireless embedded systems In this article, we will explore tips and techniques for hunting noise sources using a new type of instrument called the mixed domain oscilloscope, or MDO. View the full article HERE.
Design concerns and global opportunities for TV With an overview of the global TV market, Alan Hansford of Silicon Labs explains how silicon TV tuners enable economical, flexible TV architectures View the full article HERE.
How does DECT fit in the wireless market? What exactly is ultra low power DECT? And where does it fit in to the wireless landscape. I asked Jos van der Loop of Dialog Semiconductor to respond. View the full article HERE.
Hands On: Improve performance in RF transceiver designs This paper describes ZIF and superheterodyne receiver differential interfaces for the demodulator, IF VGA, mixer, and analog port of the ADC, as well as transmitter differential interfaces between the TxDAC and FMOD, using Analog Devices parts for active portions of the signal chain. Gain calculations and simulation results are presented for the application filters that were designed for these circuits. View the full article HERE.
Options for simulating wideband signals The need to take baseband signals and modulate them onto higher frequency carriers is fundamental for both the design and evaluation of communication and radar systems. How do we go about modulating and then upconverting wideband signals to their operational carrier frequencies for simulation? View the full article HERE.
