FeaTures DescripTion
2GHz to 14GHz Microwave
Mixer with Integrated
LO Frequency Doubler
The LT C
®
5549 is a general purpose passive double-
balanced mixer that can be used for upconversion or
downconversion. The RF port is designed for the 2GHz to
14GHz band and the IF port is optimized for 500MHz to
6GHz operation. An integrated LO buffer amplifier supports
LO frequencies from 1GHz to 12GHz, requiring only 0dBm
LO power. The LTC5549 delivers high IIP3 and input P1dB
with low power consumption.
An internal LO frequency doubler can be enabled by a
CMOS-compatible digital control pin, allowing operation
with a lower, one-half LO input frequency. This allows the
mixer’s LO port to be used with existing synthesizers, such
as the LTC6946 and LTC6948 family.
The LTC5549’s high level of integration minimizes the total
solution cost, board space and system level variation with
its 2mm × 3mm package size.
