DescripTion
The
LTC
®
5553
is a high performance, microwave double
balanced passive mixer that can be used for frequency
upconversion or downconversion.
The LTC5553’s mixer and integrated RF balun are optimized
to cover the 3GHz to 20GHz RF frequency range. The
device includes an integrated LO amplifier optimized for
the 1GHz to 20GHz frequency range, requiring only 0dBm
drive. The integrated IF balun is optimized to cover a very
wide, 500MHz to 9GHz, frequency range while providing
a single-ended 50Ω interface.
The LTC5553 delivers exceptionally high IIP3 and P1dB,
in addition to low LO to RF and LO to IF leakages. The part
also offers a high level of integration in a small package.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
The LTC5553 is guaranteed functional over the –40°C to 105°C
case temperature range (θ
JC
= 25°C/W).
Note 3:
SSB noise figure measurements performed with a small-signal
noise source, bandpass filter and 2dB matching pad on input, with
bandpass filters on LO, and output.
