High-speed digitizers are changing the way high-frequency systems designers approach receiver architectures. Rather than rely on the traditional mixer-based frequency-conversion receiver layout, high-performance analog-to-digital converters (ADCs) make it possible to eliminate some or all mixer stages. In fact, they open the door to a direct-conversion receiver approach, whereby input signals are filtered, amplified, and then digitized...
