The ATR0797 is a multi-purpose demodulator RFIC. The silicon monolithic integrated circuit is designed with Atmel's advanced SiGe technology. This demodulator is capable of both quadrature demodulation or direct IF output. Features include switchable gain control on a frequency range from 65 MHz to 300 MHz. The device performs a very low amplitude as well as phase error and allows high input P1dB. The ATR0797 targets a variety of system applications for communications including 3G wireless. Figure 1.
