Abstract:

Power amplifiers (PA) are typically the most power-consuming building blocks of RF transceivers. Therefore, the design of a high-efficiency radio frequency power amplifier is the most obvious solution to overcoming the battery lifetime limitation in the portable communication systems. A power amplifier's classes (A, AB, B, C, F, E, etc), and design techniques (Load-pull and large-signal S-parameters techniques) are presented. The design accuracy of class-A power amplifier based on the small-signal S-parameters was investigated, where compression in the power gain was used as an indicator fo

Abstract:

Modern wireless communication systems transmit complex modulated signals with high peak to average ratio in order to deliver high data rates. It demands wide bandwidth and rigorous efficiency performance for power amplifiers. Today’s conventional RF power amplifiers have relatively poor operating efficiency and require more power and area for operation. Therefore, more research on high efficiency power amplifier is crucial to the growth of the wireless industry. Until recent days, WiMAX systems are using technology processes such as Gallium Arsenide (GaAs) and Si LDMOSFET to obtain the perform

Abstract:

This thesis discusses the design, construction and testing of a highefficiency, 100 MHz, 1 kW, Class-E solid state power amplifier. The design was performed with the aid of computer simulations using electronic design software (ADS). The amplifier was constructed around Ampleon's BLF188XR LDMOS transistor in a single ended design. The results for 100 MHz operation show a power added efficiency of 82% at 1200 W pulsed power output. For operation at 102 MHz results show a power added efficiency of 86% at 1050 W pulsed power output. Measurements of the drain- and gate voltage waveforms provide va

Abstract:

In retrospect we can see that from the last century, wireless electronic technology has been in a rapid state of development. With the popularity of wireless communication, the power amplifier demand is rising. In general, magnitude, maximum noise figure, minimum noise figure, efficiency, and output power are important indicators of the amplifier. The IC industry is exploring how to reduce the additional cost and improve the high-frequency performance. Therefore, designing a strong adaptability and high cost performance of the PA has become a priority. As these technologies advance, the power

This study investigated the Class-E power amplifier operating at 5.2 GHz. Since the operation of this amplifier applies a lot of stress on the switching transistor, a cascode topology was applied in order to reduce the drain-source voltage stress.

A layout for the said design was then created to be fabrication-ready using the TSMC 0.18 um technology. Post-layout simulations were performed in order to realize a more realistic circuit performance with the layout design in mind. Long-

In this circuit, the pulse width modulation is served as the main structure in which an L-C resonant circuit is included for voltage filtering and soft-switching. An impedance-matching circuit is then added between the resonant circuit and load so that the maximum power transfer to the load can be realized. To validate the feasibility, mathematical derivations were made with theoretical simulations and experimental validations. Test res

碩士<br>國立清華大學<br>電子工程研究所<br>104<br>Nowadays, polar modulation transmitter is a popular research topic. In this architecture, a RF signal is separated into two parts: its amplitude and phase. The phase component is fed into a power amplifier, and the amplitude component is fed into a control circuit that modulates the supply voltage of the power amplifier accordingly. Thus in a polar modulation system, it is allowed to use a highly non-linear power amplifier such as a class-E amplifier. Compared to ordinary power amplification, this architecture favors both high linearity and power-added-efficie

碩士<br>國立交通大學<br>電子工程系所<br>96<br>A first X-Band fully integrated Class-E power amplifier is proposed in this thesis and fabricated in 0.18-�慆 CMOS technology. Injection locking technique is applied to help the reach of the X-Band operation. Measurement results show that the proposed Class-E power amplifier could achieve 17% power added efficiency (PAE) and delivering an output power of 10.75dBm with gain 20dB at 8.41 GHz. Also, the PAE is over 14% over the frequency range 8.35 GHz to 8.45 GHz. In order to improve the modulation accuracy of the proposed circuit under the EER transmitter, a compe

Abstract:

碩士<br>國立交通大學<br>電子工程系所<br>96<br>In order to obtain moderate chip area, high output power, and high power efficiency simultaneously, nonlinear Class-E power amplifier should be the best choice. Cascode Class-E PA provides better power-added efficiency (PAE) than any other topologies such as differential, common-gate, or common-source. Although Class-E power amplifiers have high power-added efficiency (PAE), poor harmonic suppression would make the whole communication system with nonlinear power amplifier be out of transmission specification. To conquer the drawback of nonlinear power amplifier,

Its output power and power-added efficiency (PAE) in wireless communication system has the dominant impact, especially in the performance and efficiency of the system. A class-E power amplifier provides the higher PAE and allows the operation of this system in partial non-linearity. Thus, the RF design system obtains the more elasticity.
