LTC5552
3GHz to 20GHz Microwave
Mixer with Wideband DC to 6GHz IF
FEATURES
DESCRIPTION
The LTC®5552 is a high performance, microwave double
n
Integrated LO Buffer: 0dBm LO Drive
n
50Ω Wideband Matched RF and LO Ports
Wide IF Bandwidth: DC to 6GHz
Upconversion or Downconversion
High IIP3:
balanced passive mixer that can be used for frequency
upconversion or downconversion. The device is similar
to the LTC5553, but with a broadband, differential DC to
6GHz IF port. The LTC5552 is recommended for applica-
tionswheretheIFfrequencyrangeextendsbelow500MHz.
For applications where the IF frequency is always above
500MHz, the LTC5553 is recommended, since it includes
an integrated IF balun.

The mixer and integrated RF balun are optimized to cover
the 3GHz to 20GHz RF frequency range. The integrated LO
amplifier is optimized for the 1GHz to 20GHz frequency
range, requiring only 0dBm drive.
APPLICATIONS
The part delivers high IIP3 and P1dB, low LO leakage and
high integration in a small package.
