Product Overview

The LT5575EUF#PBF is a 800MHz to 2.7GHz direct conversion Quadrature Demodulator optimized for high linearity receiver applications. It is suitable for communications receivers where an RF signal is directly converted into I and Q baseband signals with bandwidth up to 490MHz. The LT5575 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadrature phase shifter. The integrated on-chip broadband transformers provide 50R single-ended interfaces at the RF and LO inputs. Only a few external capacitors are needed for its application in an RF receiver system. The high linearity of the LT5575 provides excellent spur-free dynamic range for the receiver. This direct conversion demodulator can eliminate the need for intermediate frequency (IF) signal processing, as well as the corresponding requirements for image filtering and IF filtering. Channel filtering can be performed directly at the outputs of the I and Q channels.
