Housed in SSO and QFN packages, the ATR4251 AM/FM antenna amplifier IC enables high AM/FM car-radio reception when used with designer antennas, such as windshield, roof, or bumper antennas. Its reception quality is due to the balance of an AM gain value of up to 35 dB, a large-signal behavior both in AM and FM mode, and a good noise behavior, optimized for antenna applications.
A separate LNA for FM and a buffer amplifier for AM are used to address the different operating frequencies and requirements of both AM and FM. The AM amplifier covers the entire broadcasting frequency range from 150 kHz up to 30 MHz, which includes modern DRM systems, while the FM LNA handles the frequency range from 70 to 166 MHz, which includes weather band and HD radio in the U.S. ($0.60 ea/100,000available now.)
