Keysight Technologies recently introduced the N7614B Signal Studio for Power Amplifier (PA) Test aimed at improving PA efficiency.
The N7614B Signal Studio supports crest factor reduction (CFR), envelope tracking (ET) and digital pre-distortion (DPD) technologies which are often used to minimize PA power consumption and reduce nonlinearity.
PA test is a critical step during R&D and the manufacturing of wireless mobile devices.
The company said N7614B is cost-effective for Keysight’s customers since they can now perform PA test within hardware and there’s no need to acquire new software. The N7614B software also supports API programming, enabling it to be easily integrated into a customized PA test system.
The N7614B software provides a flexible I/Q waveform interface that can be Signal Studio generated waveforms, or customer-provided MATLAB waveforms. Engineers use these waveforms as input into the PA when making measurements during test.
Based on the results, the PA can then be adjusted to improve its output signal quality using CFR, ET and DPD technologies.
Kurt Philipsen, applications marketing manager for Keysight’s Microwave and Communications Division, said: “While most PA test solutions require the engineer to purchase new test equipment and create their own custom RF test signals, Keysight’s new N7614B allows them to use their existing equipment.”
Meanwhile, Keysight Technologies announced membership in the Korea 5G Forum, a collaborative development environment for 5G wireless communication. The forum cooperates internationally on standardization, research and development, and in creating an ecosystem for the next generation of wireless communications.
