FeaTures DescripTion
2GHz to 14GHz
Microwave Mixer with
Wideband DC– 6GHz IF
The LT C
®
5548 is a high performance, microwave double
balanced passive mixer that can be used for frequency
upconversion or downconversion. The device is similar
to the LTC5549, but with a broadband, differential DC to
6GHz IF port. The LTC5548 is recommended for applica
-
tions w
here t
he IF frequency range extends below 500MHz.
For applications where the IF frequency is always above
500MHz, the LTC5549 is recommended, since it includes
an integrated IF balun.
The LTC5548’s mixer and integrated RF balun are opti
-
mized to
cover the 2GHz to 14GHz RF frequency range.
The
device includes an integrated LO amplifier optimized
for the 1GHz to 12GHz frequency range, requiring only
0dBm drive. The device also includes an integrated LO
frequency doubler, which can be enabled or disabled with
a CMOS-compatible control pin.
The LTC5548 delivers exceptionally high IIP3 and P1dB,
in addition to very low LO to RF and LO to IF leakages.
The part also offers high integration in a small package.
