R&S offers a load pull test setup with wideband modulated signals using the RTP oscilloscope for non-linear device characterization. Compared to conventional vector network analyzers, this setup ...

In general terms, power amplifiers (PAs) used in communications systems must be large enough to amplify envelope peaks. This leads to amplifiers designed to offer the best efficiency at peak power ...

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 ...

Mesuro announced the introduction of its MB Series active load-pull systems at IMS 2009. The MB Series enables device and power-amplifier manufacturers to characterize their devices within an ...

Engineers designing motion-control devices have a long list of standard, off-the-shelf options to choose from, everything from balls screws to electromagnetics. But the list shrinks dramatically if ...
