Part Number: ADC12DJ5200RF
Dear Experts,
Pl. help me to find answer below question.
ADC related:
1. What is technology which is helping to increase sampling speed in GHz rate compared to earlier days' MHz rate?
2. What is hindrance in ADC Technology/Processes so that sampling cannot be done beyond 8GHz Analog RF Signal (for example, 12DJ5200RF RF ADC TI) ?
Track-Hold Amplifier related:
As you are aware that Track-and-Hold Amplifier like HMC661 (Analog Devices) has drastically extended analog bandwidth of GHz ADC upto 18GHz . My queries are
3. What is basic difference between existing Sample-and-Hold(SnH) vs newly introduced Track-and-Hold(TnH)? Any advantage of newly introduced TnH over SnH?
4. Earlier days, Sample-and-Hold was part of ADC technology and kept inside ADC. Why few TnH technology cannot be combined with ADC so that it becomes part of ADC and samples upto 20GHz, say?
Best Regards,
Sounak.
