Product Description:

1. The antenna array is composed of a two-layer structure, the upper layer is an antenna array composed of 12 units, and the lower structure includes a calibration network and 12 dual-channel low noise amplifiers;

2. 12 units are arranged according to 2×6 to form a rectangular plane array, and each unit is composed of two orthogonal double-polarized symmetric oscillators to form left-right double-polarization;

3, each dual low noise amplifier contains two identical amplification branches, respectively, the antenna received left circular polarization and right circular polarization signal for low noise amplification and filtering;

4. The calibration network distributes the input reference signal to 12 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;

5, amplifier circuit gain is high, low noise factor, with high dynamic reception function;

6, antenna and circuit do three protection treatment;

7, unique waterproof and dustproof design, to meet the waterproof IP67, to ensure that the core units and components are completely sealed, to meet the complex outdoor environment, can work normally outdoors for a long time.
