M/A-COM has launched a pair of new low-cost 2-stage driver amplifiers, the MAAMSS0072 and MAAMSS0073, to extend its successful family of broadband, high linearity driver amplifiers. The broad frequency range, high linearity and reliability make this M/A-COM product family ideally suited for a variety of wireless applications such as WiMax,WiBro and UMTS/WCDMA Basestations.

## Abstract We have designed and realized a highly linear power amplifier module (PAM) for a WiMAX/WiBro base station using a simple linearization method. To improve the linearity of the PAM, we use largeβsignal intermodulation distortion (IMD) sweet spots, which are part of the inherent properties
## Abstract In this article, we propose a highly linear and efficient twoβstage GaN HEMT asymmetrical Doherty power amplifier (ADPA) for WCDMA applications. The firstβstage driving DPA not only improves the linearity as the predistortion circuit but also reduces the power consumption in the driving
## Abstract In this article, we propose a highly linear and efficient threeβway Doherty amplifier using twoβstage GaN HEMT cells for repeater systems. The driving cells are used as the predistortion circuit to improve linearity as well as the gain stage. The main cells are optimized to achieve high
We present a theoretical analysis and experimental results for the most suitable configuration of pump power in a two-stage erbium-dopedfiber amplifier. The amplifiers are arranged in a copropagating pump scheme and use large signal input and modest pump power. Experimental results are in good agree
