DESCRIPTIO
The LT®5560 is a low power, high performance broad-
band active mixer. This double-balanced mixer can be
driven by a single-ended LO source and requires only
–2dBm of LO power. The balanced design results in
low LO leakage to the output, while the integrated input
amplifier provides excellent LO to IN isolation. The sig-
nal ports can be impedance matched to a broad range
of frequencies, which allows the LT5560 to be used as
an up- or down-conversion mixer in a wide variety of
applications.
The LT5560 is characterized with a supply current of 10mA;
however, the DC current is adjustable, which allows the
performance to be optimized for each application with a
single resistor. For example, when biased at its maximum
supply current (13.4mA), the typical upconverting mixer
IIP3 is +10.8dBm for a 900MHz output.
