The ANADIGICS upconverter MMIC is a low-cost, high performance upconverter fabricated entirely in GaAs. It is designed for use in double conversion CATV set-top converters, cable modems and TV receiver tuners. upconverter offers a high degree of functionality in a very small and user friendly configuration. The MMIC provides tuner manufacturers the opportunity to reduce cost by lowering the component count and decreasing the amount of production alignment steps, while significantly improving performance and reliability.
