| RF SILICON AND SUBSYSTEMS SOLUTIONS FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS MT1119 AUTOMOTIVE AM/FM ANTENNA AMPLIFIER SUBSYSTEM PRELIMINARY PRODUCT BRIEF The MT1119 is a highly integrated and complete RF amplifier subsystem for active AM/FM antennas MT1119 High Performance Automotive AM/FM Amplifier Subsystem The MT1119 is an advanced, lowpower, highly integrated single-chip amplifier IC specifically designed for automotive AM/FM antenna systems requiring low noise and very low distortion. Additionally, the MT1119 has an integrated true-RMS power detector and an uncommitted op-amp in order to realize an AGC function for FM by simply adding external PIN diodes. The threshold of the FM AGC function is variable and can be set according to the application requirements. The onchip 2.5V temperature compensated reference generator and high output voltage op-amp combine to form a low-cost, reliable, automotivecapable power supply which can be directly derived from the car battery. The MT1119 is capable of amplifying signals with frequencies in the 0.15 MHz to 30 MHz range for AM and 76 MHz to 162.4 MHz range for FM. External components determine the gain of the AM and FM amplifiers and can also be modified to extend the operating frequency of the MT1119. The AM amplifier uses a highly sophisticated design technology in order to reach low noise, very low distortion, high input impedance and its capability to drive very low output impedance. The FM amplifier is matched to 50 ohms and is specially designed to perform with very low noise and distortion. The small 24-pin QFN package of the MT1119 and the requirement for minimal external components enables a compact, cost-effective solution fulfilling automotive requirements.
