FPGA Implementation of a Hammerstein Based Digital Predistorter for Linearizing RF Power Amplifiers with Memory Effects
Power amplifiers (PAs) are inherently nonlinear elements and digital predistortion is a highly cost-effective approach to linearize them. Although most existing architectures assume that the PA has a memoryless nonlinearity, memory effects of the PAs in many applications ,such as wideband code-division multiple access (WCDMA) or orthogonal frequency-division multiplexing (OFDM), can no longer b...
متن کاملCITY UNIVERSITY OF HONG KONG 香港城市大學 Study on Innovative Integrated Power Amplifier/Low Noise Amplifier/Switch for Wireless Application
The front-end transmit/receive switch circuit is one of the essential elements in modern wireless handsets. The main function of the transmit/receive switch is switch the antenna either to the transmitter or the receiver. It must have high isolation in order to avoid the RF-power of the transmitter (PA) turning on the receiver (LNA), resulting in high loss or in the worst case damage. Low inser...
متن کاملFormulation of Least-Cost Dairy Ration for Small-Scale Dairy Farms Using ‘Solver Add-Ins’ in Microsoft Excel
Small-scale dairy farming in Bangladesh is constrained mostly due to acute shortage, high price and seasonal fluctuation of energy and protein supplements. Poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. Locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

متن کاملResults and Lessons Learned from Conditioning 1 Mw Cw 350 Mhz Coaxial Vacuum Windows
The reliability of the radio frequency (RF) windows on the Low Energy Demonstration Accelerator (LEDA) is critical to the success of the Accelerator Production of Tritium Program (APT). On the APT accelerator there will be over 1000 windows, each passing on the order of 250 kW of CW RF power. This power level is well above power levels historically used in RF windows. Based on the high-power RF...
