MIXED TECHNOLOGY MEMS/SIGE BICMOS DIGITIZING ANALOG FRONT END WITH DIRECT RF SAMPLING |
摘要 |
A digitizing analog front end (DAFE) (50) using mixed technology on a single substrate is described. SiGe BiCMOS technology is implemented for the semiconductor components, which include a low noise amplifier (64) and an analog-to-digital converter (68). Micro Electro Mechanical System (MEMS) switches are used to change the filtering characteristics of several filters, including an anti-aliasing filter (66) and a pre-select and anti-jamming filter (62). |
