High Linearity Active

Upconverting Mixer

FeaTures

DescripTion

The LTC^®5576 is a high linearity active mixer optimized for

upconvertingapplicationsrequiringwideinputbandwidth,

low distortion and low LO leakage. The integrated output

transformer is optimized for 4GHz to 6GHz applications,

butiseasilyretunedforoutputfrequenciesaslowas3GHz,

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.

Broadband 50Ω Matched Input

High Input P1dB: 10dBm at 5V

5V or 3.3V Supply at 99mA

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.

16-Lead (4mm × 4mm) QFN Package

The LTC5576 is optimized for 5V but can also be used

with a 3.3V supply withslightly reduced performance. The

enable function allows the part to be easily shut down for

further power savings.
