提出了一款5 位倍频程延时组件,集成谐波抑制、自动增益控制和收发驱动放大功能。幅度均衡和带通滤波功能的存在便于宽带使用场景。基于高温共烧陶瓷,逻辑控制和收发链路分置于独立的腔体中,以避免串扰自激。因此该组件可实现83 ps 分辨率最大2. 58 ns 延时量,同时接收增益约12 dB,带内起伏在±2 dB 以内,输出功率高于0. 5 W。此款延时组件可以通过球栅阵列植球焊接在印制板上,便于相控阵系统的小型化和高集成。

In this paper, an 5-bit octave true time delay (TTD) module is proposed. Besides, function including harmonic suppression, automatic gain control (AGC), and TR amplifying are integrated. Therefore, amplitude equalizer and band-pass filter are utilized for wideband application. On a basis of high temperature co-fired ceramics (HTCC), logical control and RF receiving/ transmitting circuits can be mounted in discrete cavities for avoiding of interference and resonance. In this way, a true time delay module with 2. 58 ns range and 83 ps resolution is designed. Moreover, receiving gain reaches 12 dB within ±2 dB fluctuation and transmitting power is more than 0. 5 Watt. Accordingly, the module can be assembled to printed circuit board though ball grid array (BGA), which is tailored to compactness of active phased array radar system.
