Anadigics, Inc. announces its ABA3130, a single-chip, low-noise, high linearity RF amplifier with integrated gain control for cable TV front end applications. Designed to replace existing discrete solutions, the fully integrated amplifier improves receiver performance in a number of cable TV digital set-top boxes and analog and digital TVs. To ensure compatibility with tuners being developed for future 1 GHz cable systems, the amplifier features wideband operation of 50 MHz to 1.1 GHz. It exhibits a typical noise figure of 4.5 dB at 5 dB gain, enabling clearer analog pictures and better reception on digital channels. It also offers a wide dynamic gain control range of 37 dB to prevent overloading tuner front ends.
