JAJSEY1C April 2019 – March 2022 ADC12DJ5200RF
This section demonstrates the use of ADC12DJ5200RF as a wideband RF sampling receiver. The solution is flexible and can be used as either a 2-channel receiver (such as a diversity receiver) or as a single channel receiver allowing double the signal bandwidth. The ADC is driven by single-ended RF amplifiers and the conversion to differential signaling is achieved by a transformer (balun). The device includes digital down-converters (DDCs) in both single-channel and dual-channel modes to mix the desired frequency band to baseband and down-sample the data to reduce the interface rate. The block diagram for the wideband RF sampling receiver is shown in Figure 8-1 with the device is configured in single-channel mode for maximum signal bandwidth.
