- The FBDA is installed near the area to be covered and is connected to the mobile antenna. A Fiberoptic transceiver converts the Downlink optical signals to RF signals and the uplink RF signals to optical signals. A duplexer in the FBDA separates the upli
- of the same antenna for receiving and transmitting. The duplexer has sharp out of band attenuation for better isolation between the receiving and
- transmitting paths and for reduction of out of band interfering signals. A high power amplifier in the downlink path produces high RF power to the antenna. A LNA (low noise amplifier) is used to drive the uplink signals from the antenna to the Fiberopt
- For diversity applications the uplink path is duplicated using separate antenna, filter, LNA and Fiberoptic transmitter.
