The LT
5516 is an 800MHz to 1.5GHz direct conversion
quadrature demodulator optimized for high linearity re-
ceiver applications. It is suitable for communications
receivers where an RF or IF signal is directly converted into
I and Q baseband signals with bandwidth up to 260MHz.
The LT5516 incorporates balanced I and Q mixers, LO
buffer amplifiers and a precision, high frequency quadra-
ture generator.
In an RF 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. Channel filtering
can be performed directly at the outputs of the I and Q
channels. These outputs can interface directly to channel-
select filters (LPFs) or to a baseband amplifier.
