Description
The ATR0797 is a multi-purpose demodulator RFIC. The silicon monolithic integrated
circuit is designed with Atmel鈥檚 advanced SiGe technology. This demodulator is capa-
ble 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.
