Development of a Novel Low Profile Receiving Module in Ku-band and Integrated Antenna

Abstract

In order to meet the needs of high-performance active phased arrays, a new type of 64-channel dual-polarized low profile receiver module in the Ku frequency band with a Z-axis profile thickness only 13mm was designed, by using micro-assembly technology. Antenna is integrated on the back of the module, which can greatly reduces the size of the RF transmission direction of the terminal module. The radio frequency signal at the antenna end is interconnected with the microwave substrate through gold wire bonding. The test results of one hundred and twenty-eight polarized RF channels are consistent cover the design indicators, the noise figure of the receiving link is less than 4dB, the single-polarized channel gain is tested around -10dB, so the total gain of the module is greater than 27dB. The component weight is less than 200g, and the component size is 96mm*96mm*13mm.
