1、The antenna part adopts symmetrical design to minimize the impact of the precision error and ensure the phase center stability.
2、The unit features a multi-feed design, offering high gain, a wide directional beam, and excellent low-elevation signal reception, ensuring normal reception in special occasions where the signal is severely obscured.
3、Transmitter circuit amplifier module is equipped with a power detection module, which is closed under the pure reception mode to reduce power consumption effectively. Meanwhile, the final stage amplifier with charging protection circuit can protect the amplifier tubes from breakdown damage under over-voltage and saturated input power.
4、The receiving circuit is equipped with front cavity filter to enhance the whole anti-jamming ability of antenna reception.
5、The antenna adopts single-port output to supply power and transmit RF signals at the same time, which greatly enhances the system integration.
