Modified Doherty Power Amplifier for Wider Band
Wireless communication system are developing rapidly, due to which new standards like WIMAX and 4G Long Term Evaluating(LTE) with a purpose of achieving high data rate result in high end applications such as high speed internet, video conferences and broadband width. These applications require mobile base stations at the transmitter as well as at receiver (T/R) to support features like multiple...
متن کاملLTE-Advanced System Level Simulation Platform for IMT-Advanced Evaluation
International Mobile Telecommunications (IMT)Advanced is the new global standard defined by the International Telecommunication Union (ITU) for the fourth generation of mobile communication systems. Several technologies like Long Term Evolution (LTE)-Advanced have been proposed as IMT-Advanced candidates. In order to achieve this consideration, evaluations must ensure the achievement of a set o...
متن کاملA High Efficiency Doherty Amplifier with Digital Predistortion for WiMAX
The Doherty amplifier architecture is a well known technique offering the potential to improve transmitter efficiency especially for signal protocols that exhibit high peak-toaverage power ratios. Although the Doherty approach has significant efficiency advantages, it generally must be augmented with some form of correction or linearity enhancement in the full transmitter design. Wireless infra...
متن کاملA Symmetrical Optimized Doherty Power Amplifier for LTE Band41
A symmetric Power Amplifier with an optimized impedance quarter wave transmission line is presented using a thermally enhanced high Power LDMOS FET i.e. a 140W Infineon PTFC261402 device. This implementation is realized in the operating frequency of LTE Band41 (2.496GHz-2.69GHz) applicable for LTE base stations. This design achieves a high efficiency that persists for an output power back off r...
متن کاملLinearization of Three-Stage Doherty Amplifier
In this paper, the operational behavior of three-way Doherty amplifier loaded with harmonic control circuits is analyzed, including the efficiency and linearity. Amplifier is designed in configuration with two quarter-wave impedance transformers in the output combining circuit with LDMOSFETs in carrier and peaking amplifiers with the same periphery and in periphery relations 1:2.5:2.5. The sign...
