LTC5549IUDB#TRMPBP RF Mixer 2GHz to 14GHz Microwave Mixer w/ Int LO

The LTC5549 consists of a high linearity double-balanced
mixer core, LO buffer amplifier, LO frequency doubler
and bias/enable circuits. See the Block Diagram section
for a description of each pin function. The RF, LO and IF
are single-ended terminals. The LTC5549 can be used
as a frequency downconverter where the RF is used as
an input and IF is used as an output. It can also be used
as a frequency upconverter where the IF is used as an
input and RF is used as an output. Low side or high side
LO injection can be used. The evaluation circuit and the
evaluation board layout are shown in Figure 1 and Figure 2,
