Abstract

In this paper, we present design, implementation and measurement of 3D mm-wave LTCC (low temperature co-fired ceramic) module with vertical transition through FR-4 PCB substrate. A new structure in order to transfer mm-wave signal from transceiver module through an opening in FR-4 PCB substrate to antenna with standard WR-22 waveguide port is proposed. The module features front-end, receiver and transmitter. The opening in FR-4 PCB substrate is of rectangular type, which has the same dimensions as a WR-22 waveguide. The edge of the opening is conductively plated with copper from top side to the bottom to reduce transmission losses. The implemented module is compact in size (32 x 28 x 3.3 mm ). Experimental results show a 1dB compression output power of 15 dBm and noise figure of 9.72 dB at 40.5~41.5 GHz.
采用LTCC技术的40GHz收发模块垂直过渡设计
在本文中,我们介绍了3D毫米波LTCC(低温共烧陶瓷)模块的设计、实现和测量,该模块具有垂直跃迁通过FR-4 PCB基板。提出了一种将毫米波信号从收发模块通过FR-4 PCB基板上的开口传输到具有标准WR-22波导端口的天线的新结构。该模块包括前端、接收机和发射机。FR-4 PCB基板中的开口为矩形型,其尺寸与WR-22波导相同。开口边缘由上至下导电镀铜,以减少传输损耗。实现的模块尺寸紧凑(32 x 28 x 3.3 mm)。实验结果表明,在40.5~41.5 GHz频段,1dB压缩输出功率为15 dBm,噪声系数为9.72 dB。
