  5. Model-Based GaN PA Design Basics: The What And Why Of Intrinsic I-V Waveforms (Part 3)
    10/18/2018

    Understanding the impact and nuances of I-V curves is a fundamental part of learning how to design GaN power amplifiers. This is the third part in an ongoing series looking at the importance of GaN HEMT nonlinear models for rapid power amplifier (PA) design success.

  6. 5G/4G Combined Antenna Analysis In A Smartphone Using EM Simulation
    10/17/2018

    This example uses XFdtd® EM Simulation Software to analyze the performance and interaction of two antenna systems operating at 4G (860 MHz) and 5G (28 GHz) in close proximity in a smartphone design. The 4G antenna is intended to produce a broad pattern for wide coverage while the 5G array should produce narrow beams that can be steered by varying the phasing between elements. The 4G antenna is an inverted-L design and is located at the top of the phone. The 5G antenna array consists of four Yagi-Uda elements that are near the 4G antenna but offset by a conducting block.
