FeaTures DescripTion
3GHz to 8GHz
High Linearity Active
Upconverting Mixer
The LT C
®
5576 is a high linearity active mixer optimized for
upconverting applications requiring wide input bandwidth,
low distortion and low LO leakage. The integrated output
transformer is optimized for 4GHz to 6GHz applications,
but is easily retuned for output frequencies as low as 3GHz,
or as high as 8GHz, with minor performance degradation.
The input is optimized for use with 1:1 transmission-line
baluns, allowing very wideband impedance matching.
The LO input port is single-ended and requires only 0dBm
of LO power to achieve excellent distortion and noise per
-
formance while also reducing circuit requirements. The
LTC5576
offers low LO leakage, reducing the demands
of output filtering to meet LO suppression requirements.
The LTC5576 is optimized for 5V but can also be used
with a 3.3V supply with slightly reduced performance. The
enable function allows the part to be easily shut down for
further power savings.
