Abstract: The composition principle, design method and measure result of a miniaturized and high integrated active antenna interface network is introduced. The difficulties of miniaturization and high integration are evaluated. High integration scheme is proposed based on multilayer printed circuit and micro-assemble technology. On this basis, integrated layout with six tunnels are realized, each tunnel contain transmit-receive amplification circuit and beam control circuit, used to realize independent control of transmit-receive and amplification. 10 layers stack structure is adopted by multilayer printed circuit, integrating inner monitor net work and sum-difference network. According to measured results of the module, amplitude fluctuation is better than 依0. 3 dB,transmitting saturate output power grate than 32 dBm, and weights 320 g.
