Heilbronn, Germany, June 12, 2007 Atmel® Corporation announced today the availability of the highly integrated AM/FM antenna amplifier IC ATR4251, which enables outstanding AM/FM car-radio reception when used with designer antennas, such as windshield, roof, or bumper antennas. The ATR4251’s impedance matching amplifier helps to compensate for signal losses resulting from the smaller dimensions of modern antennas and the longer cables to the car radio.

The ATR4251 IC enables crystal-clear reception without distortion even under the extremely difficult and rapidly fluctuating field strength conditions typically found in moving antenna systems due to its highly dynamic AM and FM range. This high reception quality is due to the balance of an AM gain value of up to 35 dB, a large-signal behaviour both in AM and FM mode (e.g., IP3 148 dBuV in FM), and a good noise behavior, optimized for antenna applications.
