Architecting Millisecond Test Solutions for Wireless Phone RFIC's

Today’s low cost wireless phones have driven a need to be able to economically test high volumes of complex RF IC’s at a fraction of the cost of the IC. In June of 2001 the IBM test development group developed a strategy and design to test complex wireless phone front end components for a fraction of the cost of using traditional ATE or rack and stack test solutions. In this paper the architecture of the system is described as well as some of the design, maintenance and implementation considerations. The system is designed to bring the cost of complex manufacturing test of RF IC’s equivalent to that of testing discrete components such as resistors or capacitors. Given the drastic reduction of test cost and the relative ease of implementation of this solution this architecture sets the bar for future RF test solutions. To the best of our knowledge, this architecture has resulted in the fastest RF tester in the world.
