Abstract

"Channel Emulator, which is widely used in communication system development, is an instrument that emulates the real-world signal propagation environment between transmitter and. [sic] To overcome the disadvantages of traditional channel emulator, we propose a novel structure of the automated channel emulator in Section 1, which can be controlled by software and integrated into auto-testing system. MEMS switch, with good RF performance, is used to connect and isolate multiple channels.

In Section 2, we divide the whole channel emulator system into Channel, Support, and Controller Board, and provide detailed design procedures with critical parameters of each board. The well-designed high frequency channel traces are validated by both 2D/3D simulation models and analytical calculations. The automated control logic and driven mechanism are also illustrated by sequence and block diagram.

In Section 3, we perform post-simulation after the completion of PCB layout to check the RF performance of the real PCB board. Then manufacture and assemble the whole system of the automated channel emulator.

In Section 4, we study the discontinuities in channel path in a systematically approach, including: channel trace turns, connector transient tapering, wire-bonding and solder parasitic effects. Analysis, simulations and measurements are performed to provide improvement solutions of signal transition.

Section 5 concludes this thesis work and discuss about the future plan to expand our channel emulator design to differential solution"--Abstract, page iii.
