Designing an Octave-bandwidth Doherty Am- Plifier Using a Novel Power Combination Method
In this paper, an octave bandwidth Doherty power amplifier (DPA) using a novel combiner is presented. The fundamental bandwidth limitation of the load modulation concept of a conventional Doherty structure is solved based on the proposed combination method. For verification, an octave bandwidth asymmetric Doherty architecture is implemented by using gallium-nitride (GaN) HEMT Cree CGH40010 and ...
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 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 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 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...
