Using the AD8352 as an Ultralow Distortion Differential RF/IF Front End for High Speed ADCs (cn0046)

These circuits provide both a single-ended and a differential configuration for driving high speed ADCs using the AD8352 ultralow distortion differential RF/IF amplifier. The AD8352 provides the gain, isolation, and distortion performance necessary for efficiently driving high linearity converters, such as the AD9445. This device also provides balanced outputs whether driven differentially or single-ended, thereby maintaining excellent second-order distortion levels.
