In the conventional classes of power amplifiers the efficiency drops at power back-off, whereas in order to maximize the spectral efficiency and data rate, wireless communication standards employ signals with high peak to average power ratio. This results in low average efficiency for power amplifiers, which in turn results in heavy cooling requirements and damage to the environment. To improve the low back-off efficiency Doherty technique has been widely investigated. But, the conventional Doherty power amplifiers are fairly narrowband, while

In cellular telephones, RF power amplifiers consume a significant part of the total phone current. Reducing the average PA current will extend battery life. In GSM systems the handset is commanded by the base station to transmit at power levels lower than full power much of the time. A Doherty amplifier can be used to improve efficiency at these lower power levels, providing a lower average PA current when evaluated over the entire power range. A Doherty amplifier is presented

Carrier aggregation (CA) is used in modern communication schemes to increase com- munication bandwidth (BW) and reduce redundant equipment. This combined with the already high peak to average power ratio (PAPR) signals in use for complex modulation schemes results in stringent linearity requirements and degradation in the average drain efficiency (DE) in basic power amplifier (PA) topologies. This has led to research interests in highly efficient broadband PAs capable of addressing the bandwidth and multi-standard requirements. Several techniques have been

A majority of people now have a digital mobile device whether it be a cell phone, laptop, or blackberry. Now that we have the mobility we want it to be more versatile and dependable; RF power amplifiers accomplish just that. These amplifiers take a small input and make it stronger and larger creating a wider area of use with a more robust signal. Switching mode RF amplifiers have been theoretically possible for decades, but were largely impractical because they distort
