Microchip Technology, Inc. Rf Amplifier ATR4252-RAQW

The ATR4252-RAQW is a highly integrated RF amplifier IC designed for AM and FM applications, operating within the frequency ranges of 150 kHz to 30 MHz and 70 MHz to 110 MHz. It features integrated automatic gain control (AGC) for both AM and FM, a power supply regulator, and an antenna sensor, making it suitable for active antenna systems in automotive applications. The device is built using BICMOS technology and includes separated low-noise amplifiers (LNAs) for AM and FM, ensuring high dynamic range and excellent noise performance. The ATR4252-RAQW supports adjustable FM amplifier impedance, has a low output impedance for AM, and requires only small capacitor values for AM AGC. It also boasts a high intercept point for both AM and FM signals, which enhances its performance in challenging environments. The IC is packaged in a compact 28-pin VQFN format, facilitating integration into space-constrained designs. This product is particularly well-suited for engineers looking to implement robust RF amplification solutions in automotive or similar applications.
