The immediate benefit of SiGe technology is performance. This new semiconductor process enabled the unprecedented 4 GHz bandwidth and 20 GS/second maximum sample rate. Additional benefits of SiGe include high levels of integration resulting in a robust, full featured front-end that maintains the low noise floor of previous designs while substantially increasing the bandwidth.
