High Efficiency Class-F Power Amplifier Design
Due to the high increase in and demand for a wide assortment of applications that require low-cost, high-efficiency, and compact systems, RF power amplifiers are considered the most critical design blocks and power consuming components in wireless communication, TV transmission, radar, and RF heating. Therefore, much research has been carried out in order to improve the performance of power amp...
متن کاملDesign of a Class F Power Amplifier
A Class F power amplifier (PA) at 2.5GHz has been designed and fabricated. Test results show 15.7 dB gain with 75.75% power added efficiency (PAE ), at an input level of 25 dBm. The design procedure is presented, with various issues illustrated and addressed. A new method is proposed to obtain the optimum load and source impedances without iterations, which would usually be necessary.
متن کاملElectromagnetic Stop-Band Network Improves Class F Amplifier Performance
In a class F power amplifier, producing the required short circuit at even harmonics and the open circuit at the odd harmonics at the active device output can substantially increase efficiency of the power amplifier [1, 2]. With such harmonic tuning, the voltage across the active device output and current through it do not contain harmonics of the same order simultaneously. In practice, it is v...
متن کاملDesign, Analysis and Simulation of a Linear Phase Distributed Amplifier
In this paper a new method for the design of a linear phase distributed amplifier in 180nm CMOS technology is presented. The method is based on analogy between transversal filters and distributed amplifiers topologies. In the proposed method the linearity of the phase at frequency range of 0-50 GHz is obtained by using proper weighting factors for each gain stage in cascaded amplifier topology....
متن کاملSelf-Equalized Distributed Amplifier for Wide Band Optical Transceivers
A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.
