Building on a tradition of successful products, we offer IC solutions with maximum performance, flexibility and integration level for the rapidly-expanding AM/FM active antenna market. Our antenna devices can be used in any type of antenna: pole, shark fin, short pole or glass/window antenna.

For example, the ATR4253 IC provides maximum integration to include an automatic gain control, supply voltage regulator with overvoltage protection and an antenna sensor in a 3 × 3 mm footprint. As the industry’s smallest active antenna IC, it enables you to develop smaller, high-performance antenna solutions located in the car mirror, bumper or rear or side windows.

Similar to its predecessors, the ATR4251 and ATR4252, this device enables crystal-clear reception without distortion, even under the extremely challenging conditions found in moving antenna systems.


  • Voltage regulation
  • ESD protection
  • Excellent system performance
  • Robust ambient temperature
  • Capability of up to 115°C
