The low noise receiving unit MRA21270F is designed for WCDMA /UMTS base station. It provides high gain and low intermodulation output level.
The system is suitable for outdoor mounting nearby the antenna for diversity use. DC and monitoring signals are sent through the RF cable using a bias tee.
It may be upgraded to support MCR's Control and Management System.
