Chinese Wireless Communication OEM RF PAM \ Power Amplifier\ PA Module\ Ab PA, High Efficiency Doher

High Efficiency Doherty PA and Feed Forward RF Power Amplifier1. Basic information:Wuhan Gewei Electronic Technologies provides cost effective Radio Frequency Power Amplifier solution. From 2003 to 2016, we have developed more than 350 macro-BTS RF power amplifier projects and delivered more than 3 million PA channels to our customers. Most of our modules are ZTE and ALU proven and operate in the most stringent environments on earth. With good quality and best price, our products have been supplied a world round communication operators and gain good fame.2. Product Description:The RF power amplifier includes class AB PA, high efficiency Doherty PA, feed forward PA; the band range from 0.2-3.5GHz as well as the multi-frequency band. They are mainly used for Macro-BTS, small cell and indoor & outdoor wireless network enhancement.We employ different technologies to manufacture these modules include GaN, LDMOS, GaAs and other device types to satisfy customer or internal requirements. We use discrete devices, bare die and MMIC based parts for these modules. Gewei manufactures broadband, linear, high power pulsed and very high efficiency amplifiers employed in systems such as communication, electronic warfare, test and measurements or any other application that requires high power in a small, rugged enclosure. Please view the commercial products displayed and contact us with any customized requirements you may have.3. Features:Our power amplifier products have outstanding features of high efficiency, Small size and high reliability. They have been widely used in global mobile communication networks.
