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 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 کاملDesign of Broadband Highly Efficient Harmonic-Tuned Power Amplifier Using In-Band Continuous Class(-1)/F Mode Transferring
A novel methodology for designing high-frequency broadband harmonic-tuned power ampli ers (PAs) is presented in this paper. Speci cally, a hybrid PA mode, transferring between continuous inverse Class-F and continuous Class-F, is for the rst time employed to design PAs with optimal performance over more than-an-octave bandwidth. A GaN PA is designed and realized based on this mode-transferring ...
متن کاملBroadband RF Power Amplifier Design Methodology Using Sequential Harmonic Characterization
Radio Frequency Power Amplifier (RFPA) amplifies the communication signals to the required power level for transmission. It is the most power consuming stage in a transceiver chain; consequently, any improvement in terms of dissipated power and efficiency of the power amplifier affects the overall power budget of the transmitter. Also, efficient performance of the RF power amplifier over extend...
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...
