Chain reaction

Putting a data converter and an amplifier in the same package is helping to keep pace with increasing performance and time to market demands.

Compressing design cycle time requires first time success for circuit design and board layout, yet extracting the performance from high speed, high resolution data converters often requires skills and experience that few possess.
This is especially true in high speed receivers, as part of down conversion chains in high speed instrumentation or high sensitivity wireless base stations, where the latest generation of a/d converters have sample rates in excess of 100MHz and up to 16bit resolution. Applying system in package (SiP) technology bridges the experience gap and helps keep pace with increasing performance and time to market demands.
SiP technology is commonly used in consumer applications, but has recently been applied successfully to dc/dc converters to help designers overcome difficult design challenges for a range of applications. Linear Technology is now applying this technology to high speed 16bit receivers.
Designed to achieve a high performance solution in a space saving form factor, the LTM9001 µModule receiver subsystem integrates a 16bit, 130Msample/s a/d converter with a fixed gain amplifier, anti aliasing filter and bypass capacitance.
