摘要
随着弹载雷达导引头的收发通道向着宽频带、小型化等方向发展,收发通道作为雷达导引头收发系统的核心组件,对其性能指标和体积提出了更高要求。其中,收发通道采用模块化设计,工作频率覆盖整个Ka频段,单通道体积达到110×21×2.6mm^(3),实现了收发通道的小型化、通用化、模块化设计。该文使用基于SiP技术的封装器件,运用超宽带垂直互联设计方法,采用基于铜板的新型多层板架构,解决了工作频带窄、体积大、散热难等问题。通过实验验证,该收发通道组件收发频率范围达到Ka频段,上下中频为L频段,发射通道增益25±2dB,发射功率10±2dBm,接收增益50±2dB,谐杂波抑制度可达-45dBc以上。本组件具有工作频带宽、体积小、散热快等优点,与同类产品相比,体积减小50%,具有一定的研究意义和应用价值。
With the development of missile-borne radar seekers towards wide bandwidth and miniaturization,the transmit/receive(T/R)channels,as the core part of the radar seeker's T/R system,are required to meet higher performance and size specifications.A T/R channel is designed in this paper in a modular way,covering the entire Ka-band frequency range,with a single-channel size of 110×21×2.6 mm^(3),achieving miniaturized,generalized,and modular design.This paper uses SiP-based packaged devices,employs ultra-wideband vertical interconnect design method,and adopts a new multilayer board architecture based on copper boards,solving problems such as narrow operating bandwidth,large size,and difficult heat dissipation.Test results show that the T/R channel can transmit and receive signals in the Ka-band,with upper and lower intermediate frequencies in the L-band.The T/R channel has a transmitting gain of 25±2 dB,a transmitting power of 10±2 dBm,a receiving gain of 50±2 dB,and a harmonic and spurious suppression of better than-45 dBc.The T/R channel has the advantages of wide operating bandwidth,small size,and fast heat dissipation.Compared with similar products,its size is reduced by 50%.The T/R channel has certain research significance and application value.
