Abstract :
New data aquistion components for direct conversion array radar systems have been introduced, these include: A 10 bit Analog to Digital converter (ADC) with a sample rate of 3GSps and an analog bandwidth of 5GHz giving a usable bandwidth of 1.5GHz in the L and S bands; A 12 bit Analog to Digital converter (ADC) with high performance in the L band. A 5 bit ADC with a sample rate of 20GSps and an analog bandwidth of 8GHz. Results from these components will be presented and their features, useful in array antenna systems, will be highlighted.
