In radio astronomy observations, AD converters are used to digitize the radio waves received from radio stars, performing digital signal processing to obtain the necessary observation results. To obtain even a small increase in sensitivity to nearly imperceptible radio waves, it is necessary to perform observations over a wide bandwidth. To this end, the ultrahigh-speed AD converter is capable of sampling at frequencies of up to 24GHz. In addition, as radio astronomy observations need to store radio wave phase information precisely, it is desirable for the AD converter to exhibit extremely little sampling jitter (fluctuation) during A/D conversion. This device’s most important characteristic is that it enables direct RF/IF sampling. As the analog input bandwidth to the ADC is high, analog frequency converters and optical analog transmission are unnecessary, sharply reducing device installation and maintenance costs. Device configuration comprises an ADC sampling module, DSP and other functional modules. Two types are available so the device can be divided into modules: an integrated type and a separable type. In addition, a variety of ADC module and DSP module types can be selected, ensuring optimal functionality to meet the customer’s needs.
