Product Overview

The LT5517EUF#PBF is a 40 to 900MHz Quadrature Demodulator optimized for high linearity receiver applications where high dynamic range is important. It is suitable for communications receivers where an RF or IF signal is directly converted into I and Q baseband signals with a bandwidth up to 130MHz. The LT5517 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, broadband quadrature generator derived from an on-chip divide-by-two circuit. The superior linearity and low noise performance of the LT5517 is achieved across its full frequency range. A well balanced divide-by-two circuit generates precision quadrature LO carriers to drive the I mixer and the Q mixer. Consequently, the outputs of the I-channel and the Q-channel are well matched in amplitude and their phases are 90° apart. The LT5517 also provides excellent 50R impedance matching at the 2XLO port across its entire frequency range.
