Product Description:
1, the antenna array is composed of three layers, the top layer is 48 array antenna units, receiving electromagnetic wave signals;
2, the middle layer is the calibration network, the calibration network distributes the input reference signal to 48 dual low noise amplifiers according to the principle of constant amplitude in phase; The dual-channel low noise amplifier selects the antenna signal or the reference signal through the RF switch;
3, amplifier circuit gain is high, low noise factor, with high dynamic reception function;
4, the antenna structure has enough strength to meet the vibration requirements of the ground;
5, antenna and circuit do three protection treatment;
6, unique waterproof and dustproof design, meet the waterproof IP67, ensure that the core unit and components are completely sealed, meet the outdoor complex environment, can work normally for a long time outdoors;
7, equipped with air vent valve, to ensure that the antenna working inside and outside the pressure is stable.
