Description of Wuhan Central Plains Antenna Technology Development Co Ltd trunk amplifier:
1, the trunk amplifier (model: GF-400), the 400~470M frequency range
2, the stem is placed by two high-power bandpass diplexer production, has low insertion loss (less than 1dB) output power (more than 25W), high isolation (more than 80dB), wide bandwidth (up to 3MHz) can use multiple channels (8 road combiner while using the advantages of power amplifier); using a high gain amplifier module and linear, with automatic gain control circuit can automatically adjust the size of the output according to the input signal, in the protection of the power amplifier at the same time effective and stable signal strength of the line, so that the output power is more stable.
3, the stem is also equipped with a gain adjusting module (0~20dB), truly 25W the following output power continuously adjustable, to adapt to the practical application in the project.
4, the uplink amplifier with high gain and low noise amplifier America Agilent Co, communication low noise (noise coefficient is less than or equal to 1dB), high sensitivity (gain 28dB), which decided in the whole system can be used for multiple groups of parallel, series (a series of 4 sets of dry road direction can be placed) number ten sets of dry put to use at the same time large and complex, so as to achieve the requirements of wireless coverage area.
