Leverage Circuit Envelope Simulation to Improve

Optimizing a PA design for one parameter invariably requires sacrifi cing the performance of another. This delicate balance between performance and effi ciency is not the only conundrum, because designers of 4G PAs must also contend with demands for greater instantaneous bandwidth. As a result, designers of next-generation PAs are relying on simulation more than ever before, and their tasks include frequency domain simulation, time domain simulation, and now circuit envelope simulation.

LO Harmonic Effects on TRF3705 Sideband Suppression

The LO harmonic effects on I/Q errors and sideband suppression (SBS) in the RF modulator was analyzed in application report SLWA059. This application report further investigated LO harmonic effects when attempting to achieve an increased level of SBS performance.

Statistical Analysis of Modern Communication Signals

The introduction of this digital transmission technology has made it necessary to deal with peak power levels up to 20 dB above the average value. All of the RF power components must be capable of handling these high voltage peaks to avoid break down, or flash over.

Selecting Ferrite Circulators for Radar Applications

Radar markets continue to forecast positive growth, and Skyworks Solutions offers a range of products designed specifically for these expanding markets, including materials for phase shifter applications and ferrite circulators.

Redefining RF and Microwave Instrumentation

National Instruments has redefined the traditional approach by combining PXI hardware and NI LabVIEW system design software, leveraging commercial technologies such as multicore microprocessors, user-programmable FPGAs, PCI Express hardware, and system design software to meet the flexibility and scalability demand for future high-frequency test and measurement applications.

How to Measure 5-nanosecond Rise/Fall Time in Pulsed Power Amplifiers

Rise/fall time is one of the key measurement parameters when designing, manufacturing or maintaining pulsed radar power amplifier systems, especially for wideband pulse power amplifiers. Learn how to achieve 5 nanosecond rise/fall time RF pulse measurement with the 8990B peak power analyzer by reading this application note. This article also includes tips on how to consistently obtain accurate rise/fall time measurement results.

The Advantages of Outsourcing Your RF/Microwave Assembly to an Onshore Contractor

Shifting landscapes suggest RF/Microwave companies keep manufacturing closer to home. The outsourcing decision for RF/Microwave (RF/MW) companies, however, has a unique set of circumstances when compared to conventional digital electronics.

High Temperature, High Power RF Life Testing of GaN on SiC

As GaN power device technology matures and gains acceptance suppliers must prove its reliability. This paper will provide an overview of the testing approaches used to establish failure rates and will provide a comparison of DC and RF based HTOL methods. The primary focus of this paper will be the high power RF HTOL test method used by M/A-COM Technology Solutions to qualify its new MAGX line of discrete GaN on SiC RF Power Transistors.

Voice and SMS in LTE

This white paper summarizes the technology options for supporting voice and short message service (SMS) in LTE, including circuit switched fallback (CSFB), SMS over SGs, and voice over LTE (VoLTE). It includes background information on the standardization process, and the commercial implications for the different options. The white paper also addresses test and measurement requirements resulting from the support of voice and SMS in LTE.
