MPN: FHDA
Discription: Flexi RRH 2-pipe 900 80W (FHDA)
FHDA - RF module RRH
The wireless remote module is a multi carrier power amplifier two branch, through the use of a dual channel optimization of single sector. It consists of two separate branches, for multi carrier signal to send and receive multiple wireless technology. Each branch consists of a transmitter and a receiver front-end filter chain. The wireless remote module and each branch consists of a chain of sinks. The front-end filter to cover the entire frequency band. FHxA also includes integrated antenna monitoring.
For example, the 3 sector of the RF module, remote wireless module includes such as the digital control circuit, OBSAI interface and other necessary functions of DC converter. Convection cooling fan using a remote, because it does not. In the module of the system is a common transceiver baseband part.
