... The LT5516 incorporates balanced I and Q mixers, LO buffer amplifiers and a precision, high frequency quadra- ture generator receiver, the high linearity of the LT5516 provides excellent spur-free dynamic range, even with fixed gain front end amplification. This direct conversion receiver can eliminate the need for intermediate frequency (IF) signal processing, as well as the corresponding require- ments for image filtering and IF filtering ...

... U U APPLICATIO S I FOR ATIO The LT5516 is a direct I/Q demodulator targeting high linearity receiver applications, including wireless infra- structure. It consists amplifier, I/Q mixers, a quadrature LO carrier generator and bias circuitry. The RF signal is applied to the inputs of the RF amplifier and is then demodulated into I/Q baseband signals using quadrature LO signals ...
