High-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 کاملA Tradeoff Design of Broadband Power Amplifier in Doherty Configuration Utilizing a Novel Coupled-Line Coupler
A broadband power amplifier designed and implemented in Doherty configuration is illustrated in this paper. Both input and output networks adopt the broadband matching topology. Additionally a compensation network, consisting of a series transmission line shunted with a capacitance, is set behind the peak amplifier to avoid in-band power leakage in the low-power section while at the cost of pea...
متن کاملTowards generalized Doherty power amplifier design for multiband operation
This paper presents a new variant of broadband Doherty power amplifier that employs a novel output combiner. A new parameter αα is introduced to permit a generalized analysis of the recently reported Parallel Doherty power amplifier (PDPA), and hence offer design flexibility. The circuit prototype of the new DPA fabricated using GaN devices exhibits maximum drain efficiency of 85% at 43-dBm pea...
متن کاملModified 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 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...
