doherty amplifier - measurement-aided development

this webinar introduces the doherty amplifier as a special case of the “balanced” amplifier genre. we will discuss design & test challenges and show implementation variants that make it possible to increase output power and improve efficiency.

using a dual input doherty measurement setup as a reference, we will describe a measurement-aided design method that can significantly reduce the time to market. key topics such as calibration, linear and nonlinear measurements, and analysis round out the pragmatic approach.

radio equipment directive (red) and coexistence

the efficient use of spectrum is a key-requirement of the new radio equipment directive (red). not only transmitters, but also receivers now have to meet minimum regulatory requirements and need to be tested. this discussion with an emc testing and regulatory expert goes through all relevant red regulatory, testing and co-existing topics.

basic and novel methods for the characterization of mixers with vnas – part 1

in the first webinar, you will learn how to perform a scalar characterization of the mixer and how to measure the relative phase and group delay. in addition, you get to see the technology for mixers with/without lo access.
