Class F Power Amplifier Thesis Research Papers Generation Gap

Math CAD programming is used to implement the calculations in the design of two antennas.

Good agreement between the predicted, simulated and measured results is obtained for the resonant mode frequencies, input impedance and return loss.

Each PA produced a PAE of greater than 70% and good agreement was obtained between the simulated and measured results.

The PAE obtained in these works is comparable to that reported in published papers.

A probe feed location was found to obtain the required optimum impedance at th...

Key performance indicators for high efficiency class F PA include power added efficiency (PAE) and output power (Pout). A demonstration on the direct integration of the class-F PA and an H-shaped patch antenna using an active integrated antenna (AIA) approach is also presented.To obtain a high efficiency PA, it is necessary to ensure that the power dissipated in the active device is minimised and this is achieved by ensuring that the overlapping area between the drain voltage and current waveforms in the time domain is minimised.Three PAs were designed, one operating at 0.9 GHz and the other two at 2.45 GHz.For the 0.9 GHz PA the load matching network was designed to obtain the required optimum impedances at the fundamental frequency, and second and third harmonics.In the first PA design the load and source matching networks were designed to obtain optimum impedances at the fundamental frequency and second harmonic.For the second PA design, these networks were designed to obtain optimum impedances at the fundamental frequency, and second and third harmonics.Based on this research five papers have been published in journals and conferences.An H-shaped microstrip patch antenna is used in the active integrated antenna (AIA) design.By continuing to use this site, you consent to the use of cookies.We use cookies to offer you a better experience, personalize content, tailor advertising, provide social media features, and better understand the use of our services.
