Title
(EN) Analog to digital converter module and method thereof
Abstract
(EN)

An analog-to-digital converter (ADC) module includes a plurality of frequency stacked ADCs. A splitter splits channels into two segments to transmit the signal through respective low pass and high pass filters to send the analog signal to a low frequency ADC and a high frequency ADC along each channel. When using a quad-tuner having four channels, there are eight ADCs: four high frequency ADCs and four low frequency ADCs. Typically, there is one ADC associated with each channel. Thus, a quad-tuner would be used with an ADC module having four ADCs. However, by splitting and filtering each channel and increasing the number of ADCs in the ADC module, the system, assembly, and method in the present disclosure is able to increase the frequency bandwidth throughput along legacy radio frequency (RF) cables on a platform without the need of replacing any legacy hardware or the legacy RF cables.
