LTC5585IUF#PBF

LTC5585 is a direct conversion quadrature demodulator optimized for high linearity receiver applications in the 400MHz to 4GHz frequency range. It is suitable for communications receivers where an RF signal is directly converted into I and Q baseband signals with bandwidth of 530MHz or higher. It incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadrature phase shifter. The integrated on-chip broadband transformer provides a single-ended interface at the RF input with simple off-chip L-C matching. In addition, it provides four analogue control voltage interface pins for IIP2 and DC offset correction, greatly simplifying system calibration. It is used in applications such as LTE/W-CDMA/TD-SCDMA base station receivers, wideband DPD receivers, point-To-point broadband radios, high linearity direct conversion I/Q receivers, image rejection receivers etc.
