| Abstract: |
| Aiming at the urgent need of T/R module engineering in microwave broadband active phased array system and the problems of traditional T/R module, such as insufficient bandwidth, large size, poor stability and low precision of phase shift and attenuation, this paper designs an X-Ku band broadband high-performance and high-integration T/R module. Based on the breakthrough of eight-channel module architecture design technique, the high-density integrated design technique based on LTCC entire board, high reliability and high efficiency and heat dissipation design techniques of broadband GaN power amplifier, high-frequency broadband high isolation cavity effect design technique, modularization design and mass manufacturability design technique, the X-Ku band 10～18GHz eight-channel T/R module is developed. The module has the main functions of transceiver amplification, amplitude and phase control and safety protection. The measured results show that the output power in the whole frequency band is≥23.9W, the noise figure is≤3.52dB, the phase shifting accuracy is≤3.90°(RMS), the attenuation accuracy is≤0.94dB (RMS), the standing wave ratio is≤1.98, and the efficiency is≥23%. Among them, the working bandwidth index is increased from 10～12GHz and 15～17GHz to 10～18GHz, the output power is increased from 10W to 20W, and the noise figure is decreased from 4.3dB to less than 3.52dB. This module has the characteristics of high frequency, wide band, high efficiency and high integration. It can be used in new integrated sensor radar system, multi-functional integrated electronic system, etc. |
