... Product Description 4665D–SIGE–08/04 Atmel’s ATR0797 is a variable gain I-Q demodulator designed for use in receiver IF sec- tions, that are typically existing in superheterodyne RF architectures. The ATR0797 has two gain stages that are independent of each other. These gain stages are broadband differential amplifiers each with a digital control pin to set the gain ...
