With continued pressure for increased 3G coverage for smart phones, increased Internet connection for Wi-Fi and WiMAX, and the imminent introduction of 4G/LTE systems, design activity for digital communication RF components has never been greater. At the forefront of the design activity is the development of power amplifiers (PA).
The growth of low power, cost effective wireless systems is driving more applications to use ZigBee protocol. While for some of them, the signal needs to propagate over a short range, when covering a large building or operating outdoor over a wide range for example, the system may benefit from transmitting more power.
This white paper examines the different nonlinear models and measurement systems available today and how they can be used with Microwave Office®, a leading high-frequency design environment from AWR Corporation.
When simulating a complete subsystem such as a wireless communication device or radar receiver, the quality of measurement data becomes essential to ensure that the finished product meets or exceeds the demands the system will encounter in service.
This white paper, written by EM expert Dr. John Dunn, demonstrates the importance of correctly selecting and assigning “ground” within EM simulators and how it is essential for successfully predicting the performance of board, package, and their associated interconnects.
