Design method and key technologies of a Ka band with high integration receiver module are given. In order to meet the requirement of more than 1.6 GHz instantaneous bandwidth in Ka band, true time-delay chip is integrated in the module. According to the requirement of 8 beams, a method of vertical interconnection and Radio Frequency(RF) cross technology is proposed, and the Multi-Functional Chip(MFC) technique and Multi-Chip Module(MCM) technique are also adopted to increase the integration level. Finally, a receiver module with 16 channels(8 beams) is developed successfully and NF of the module is less than 3.5 dB in the case of 10 dB attenuation. The receiver module features high integration level. It has more advantages on the size, weight and the number of beams than the conventional module.
