Product Description:
1. The antenna is a part of the digital beamforming self-tracking system. The unit adopts orthogonal symmetrical oscillator structure and hexagonal structure arrangement, and receives left-right circular double-circular polarization signals through circular polarization network;
2. The antenna is a calibration network, and the input reference signal is distributed to seven dual-channel low noise amplifiers according to the principle of constant amplitude in phase; According to the control signal, the low noise amplifier chooses the access antenna to receive the signal or the calibration reference signal;
3, amplifier circuit gain is high, low noise factor, with high dynamic reception function;
4, the antenna structure head tilt, consistent with the top of the cabin, part of the structure using stainless steel material, with enough strength to meet the vibration requirements of the aircraft.
