3 Things To Consider When Conducting High Power Amplifier Design

2016-05-25 10:58:12| rfglobalnet News Articles

AR has been designing RF amplifiers since 1969, and they’ve learned a thing or two about the intricacies of high power amplifier design in that time. Their engineering manager Rob Rowe took some time out during the first day of the IMS 2016 exhibition to share some of that knowledge with you.

Using Enhanced Load-Pull Measurements For Base Station Power Amplifier Designs

2016-05-23 11:23:18| rfglobalnet Home Page

The concept of load-pull simulation is where a load or source impedance is swept by an active device and its performance is measured. Recently, advancements have been made to data file formats by load-pull measurement system vendors to expand the usefulness of load-pull characterization. These new file formats support a sweep of an independent variable such as input power, DC bias, temperature, or tone spacing, in addition to the swept source or load impedances. The NI AWR Design Environment™ software enables designers to import and manipulate these load pull data sets in a circuit simulator which greatly simplifies and speeds the design process, and gives them a broader design space to explore. This white paper covers in-depth information on how to use enhanced load-pull measurements for base station power amplifier designs.
