12 Bit 1.5 GS/s L-Band ADC on 200 GHz SiGeC Technology

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 2
^nd
Nyquist region closer to the Antenna (L-Band), enabling the design of flexible and simplified Radar receiver system architectures.
