Development of automatic measurement system for fault detection for Ghz-band radio frequency devices

This paper proposes automatic fault measurement system for GH-band radio frequency (RF) devices. The system contains RF chip integrated with 0.18-μm BiCMOS SiGe process, control board, and PC with installed control program. The control board consists of RF Built-In Self-Test (BIST) circuit and digital signal processor (DSP). To verify performance of the measurement system we built a 1.8-GHz low noise amplifier (LNA). Proposed system helps it to provide DC output voltages, hence, making the RF system chain automatic.
