The ALNA (Advanced Antenna Low Noise Amplifier) is the integrated antenna amplifier solution for AM/FM as DAB. It offers system cost reduction through integration as well as excellent performance with its highly linear gain. One key feature is the AGC for each path with configurable thresholds.
The AGC improves the linearity of the system amplification as well as it significantly improves the radio system performance. Other built-in features include a blanking detection and antenna diagnostic features. ALNA based antenna designs offer state-of-the-art performance at a high flexibility, small form factor with great cost-effectiveness.
