Bandwidth has become more precious than gold. As we push more and more data wirelessly through our smartphones, tablets, GPS, and video players, the spectrum has become more crowded. Increasingly complex and efficient modulation schemes allow us to carry more MBits/mHz through the air. However, the key to these demanding schemes is a high fidelity signal path. Achieving high linearity and low noise while dissipating a minimum of power are keys to achieving these increased data rates within a limited spectrum and power budget. Similarly, components with built-in ease-of-use and guaranteed specifications are keys to quick, painless design cycles.
