- The duplexer serves to frequency separate uplink signals from downlink signals. The duplexer has sharp out of band attenuation for better isolation between the receiving and transmitting paths and reduction of interfering signals on air.
- This uplink amplifier contains AGC control circuitry. The amplifier has a directional coupler at its output and a detector to monitor the uplink power. When a high power signal is received the automatic level control detects the amplitude and sends a fee
- The LED on the amplifier illuminates when the power output of the amplifier is within the set limit (when the AGC is either On or OFF).
- The Switch on the RF amplifier enables the AGC function. If the AGC is disabled then the amplifier gives maximum gain for any input.
- The FBDA monitor performs the following functions:
- a) Monitors the DC supply voltage of the FBDA. The fault LED illuminates when the voltage is beyond the specified limits.
- b) Monitors the current to each active element and the internal fan. If the current is below or above the specified limits then a LED illuminates.
- c) Monitor the optical receive signal using alarm output of the optical transceiver.
- d) Provides automatic alarm function. Whenever any fault occurs or when the power is removed from the FBDA, the unit sends summarized alarm signal to the base station via the Fiberoptic transmitter data port.
- e) Provides self test for the alarm functions. The pushbutton switch on the Monitor unit turns on all the alarm LEDs and initiates the summarized alarm.
- 2.6 POWER SUPPLY
- This is a high efficiency switching power supply providing +12 VDC, up to 8 Amp.
