Product Description
The PE44951 includes highly integrated phase shifters with digitally controlled step attenuators for use across the 6.025 to 7.525 GHz frequency range. Each RF path is independently controlled through the SPI control interface. The PE44951 is ideal for wireless infrastructure applications, such as massive MIMO (m MIMO) macro and micro base stations, next-generation 5G solutions, and small cell...
