Abstract :
In advanced applications such as digital radar, Ultra Wide Bandwidth communications and software defined radio, the need for wide instantaneous bandwidth often drives system design decisions. Broadband 12 Bit ADC´s (Analogue to Digital Converters) are key enabling components which open up new design opportunities for digital Receiver systems. In this regard, this paper describes a new 12bit true single Core 1,5 GS/s ADC with 2,3 GHz Bandwidth, based on a 200 GHz SiGeC bipolar Technology, which enables the direct digitizing of 500MHz broadband arbitrary waveforms directly in the 2nd Nyquist region closer to the Antenna (L-Band), enabling the design of flexible and simplified Radar receiver system architectures.
