This paper presents a design of high RF power amplifier using Doherty technique. The objective this is to improve the efficiency 40-W feed-forward linear typically used in code division multiple access (CDMA) base-station applications. proposed uses two identical LDMOS FETs, one which biased class AB mode for carrier and other B peak amplifier. Simulation results with single CDMA signal show S.47 % improvement comparison conventional configuration. Both, as well use technique meet ACPR...
This paper presents a highly efficient modified output combining 3-stage Doherty Power Amplifier (DPA) design using low power LDMOS transistor for Band 40, TD-LTE Micro eNodeB.In this design, technique has been used in the section which meets requirements of eNodeB cannot be achieved by conventional DPA.The DPA achieves 65.3% added efficiency (PAE) at 39 dBm average with 20 MHz LTE signal 15 watt Transistor.3-stage increases linear 1.1 dB and Gain flatness versus level.The use Digital...
Increasing data capacity requirements in cellular networks have raised the demand of low-cost and energy-efficient small cells to reduce overall operating cost access network. This paper reports on development an power amplifier design for TD-LTE outdoor pico base station. The proposed uses double-stage balanced configuration by exploiting latest available process technologies low-power devices avoids commonly used a high-power LDMOS transistor. We examined conceptual through ADS SystemVue...
Macro evolved Node B (eNB) is an inevitable element to provide ubiquitous coverage for mobility in the urban area and long reach rural area. But, it consumes more than 70% of total power consumption access network. Enabling multiple efficient techniques increases efficiency eNB with cost adding non-linearity. Tradeoff between linearity while selecting combination various including peak average reduction, N-way Doherty amplifier (DPA), system integration turning on off based data traffic are...
Summary Modern cellular mobile networks are becoming more complicated and too expensive in terms of deployment, operation, maintenance. Traffic demand typically experiences spatio‐temporal variations because users' mobility usage behaviour, which lead some the cells to get overloaded without fully utilizing network capacity. To tackle these challenges, nowadays, self‐organizing (SONs) become an essential feature. This paper offers development optimization framework for SONs based on channel...
