RF and microwave devices need to operate as part of a system. Because they are typically not 50-Ω devices, they need to be matched to the rest of the system. That requires characterization of ...

Rohde & Schwarz is claiming to have invented a new test set-up for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance, by swapping the ...

Load pull characterization is an essential tool to increase the efficiency of power amplifiers. Due to time and cost, vendors have historically performed load pull during design. Today, however, the ...
