Wireless Transmitter IQ Balance and Sideband Suppression

March 14, 2012
This application note presented by Richardson RFPD discusses the major causes of nonideal sideband suppression and discusses design considerations for component selection and PCB design/layout.

Multi-tone Testing Can Save Both Time and Money

March 14, 2012
AR RF/Microwave Instrumentation has developed a product which uses a patented test process that adds additional test frequencies, or tones, for each test period, or dwell time.

Minimizing PIM Generation From RF Cables and Connectors

March 9, 2012
Understanding mechanical tolerances, coaxial design details and connector materials used in cable assemblies helps produce communications equipment with the lowest levels of passive intermodulation (PIM).

Creating a Solution for Testing Frequency-Hopping Spread Spectrum Devices

February 15, 2012
Wide bandwidth, high resolution AWGs
Measurement needs have driven the development of high-bandwidth AWGs, but they lacked accuracy and high resolution. Until now, AWG technology forced serious trade-offs between either high resolution or wide bandwidth. With the new Agilent M8190A 12 GSa/s arbitrary waveform generator, you will get both in one instrument!

Solutions for LTE-Advanced Physical Layer Design and Test

February 15, 2012
LTE-Advanced (LTE-A) is an emerging mobile communications standard that boasts a number of significant benefits, including the ability to take advantage of advanced topology networks and achieve target peak data rates of 1 Gbps in the downlink and 500 Mbps in the uplink. This white paper covers using signal generation and analysis to overcome challenges associated with carrier aggregation.

Electronically Scanned Arrays for Fast Testing of Large Antennas

February 12, 2012
This paper discuss the adaptation of the fast multi-probe technology to an existing classical planar near field facility through the manufacturing, installation and test of a partial demonstrator in Thales Alenia in Toulouse.

Leveraging OFDMA Technology for HLS Applications

February 12, 2012
In this paper we take a closer look at various OFDMA based Broadband Wireless Access (BWA) for Homeland Security (HLS) applications and their implementation. Our primary focus is to understand the capabilities required from these applications and to show how flexibility and controllability of system components can help address these requirements.

Measuring Leakage Current in RF Power Transistors

February 12, 2012
The published specifications for leakage current in RF power devices are often a source of concern and confusion for engineers and technicians. This paper examines the real meaning behind the leakage current specifications and offers guidance on properly testing a device for leakage current.

Turn up the Heat: An Electrical-Thermal MMIC Design Flow

January 17, 2012
Nov. 2011 White paper
