The LTC5594 is a ZIF demodulator with 1GHz a wideband, high linearity true zero-IF (ZIF) demodulator with 1GHz instantaneous I and Q 1dB bandwidth. The demodulator is capable of 37dB image rejection typical. Using the on-chip serial port, the device allows correction of the I and Q phase and amplitude imbalance, hence can be tuned ...
