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 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 کاملHigh-Power Inverted Doherty Power Amplifier for Broadband Application
Abstract This paper presents a high-power inverted Doherty power amplifier for broader operational bandwidth. After analyzing two operation modes according to the load modulation of the Doherty power amplifier, the inverted Doherty structure was selected. In the design, the load impedances for optimum broadband characteristics at both the back-off and peak power levels. The Doherty power amplif...
متن کاملDual Band High Efficiency Power Amplifier Based on CRLH Lines
In this paper we propose the use of Composite Right/Left Hand (CRLH) and Extended Composite Right/Left Hand (ECRLH) transmission lines for the design of dual band high efficiency power amplifiers working in CE class. The harmonic termination can be synthesized using the meta-lines is particularly suitable for CE class amplifiers, which have a termination not as sensitive to the third harmonic a...
متن کاملA Base Control Doherty Power Amplifier Design for Improved Efficiency in GSM Handsets by Darren
approved: Andreas Weisshaar In cellular telephones, RF power amplifiers consume a significant part of the total phone current. Reducing the average PA current will extend battery life. In GSM systems the handset is commanded by the base station to transmit at power levels lower than full power much of the time. A Doherty amplifier can be used to improve efficiency at these lower power levels, p...
