w DESCRIPTIO The LT®5517 is a 40MHz 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 wellbalanced divide-by-two circuit ...
