  DSOL44F01 Figure 1. Direct IF to Digital Single Conversion Receiver Wireless receiver design requires extreme care in dealing with noise sources that affect the Analog-to-Digital
  Converter (ADC). High sensitivity receivers such as
  in satellite or basestation applications demand the
  highest dynamic range and therefore need to focus on
  minimizing the noise contribution from every possible
  source (Figure 1). These include nonlinearities in the
  ADC and digital feedback from the data output bus. This
  application note will discuss the LTCВ®2208 (Figure 2), a
  16-bit 130Msps high performance pipelined ADC that is tailored for the most demanding wideband, low noise,
  receivers (Figure 3). The LTC2208 ADC addresses the
  key requirements for maximizing performance of high
  sensitivity receivers. Here we describe the application
  of its unique features to simplify receiver design and
  improve overall system performance. The first is an …
