Abstract
3-dimensional vertical interconnection structure has become the key technology of microwave integrated package which is significant for miniaturization. Fuzz button is an elastic electrical connector which can achieve solderless vertical interconnection. In this paper, a 3D multi-channel amplifier module with fuzz button based on LTCC technology is proposed. What’s more, Wilkinson power divider is designed, and two cascaded power dividers are placed on different layers to realize miniaturization. Also, fuzz buttons and vertical transition structure from strip lines to fuzz button are designed, and fuzz buttons are used as input and output port. The test results show that in 7.8~8.2GHz, the $S_{21}$ is greater than 29 dB, the standing wave of the input port is less than 1.55 and of the output is less than 1.3.
