The MAX19993 dual-channel downconverter is designed
to provide 6.4dB of conversion gain, +27dBm input IP3,
15.4dBm 1dB input compression point, and a noise
figure of 9.8dB for 1200MHz to 1700MHz diversity
receiver applications. With an optimized LO frequency
range of 1000MHz to 1560MHz, this mixer is ideal
for low-side LO injection architectures. High-side LO
injection is supported by the MAX19993A, which is pin-
pin and functionally compatible with the MAX19993.
In addition to offering excellent linearity and noise
performance, the MAX19993 also yields a high level
of component integration. This device includes two
double-balanced passive mixer cores, two LO buffers, a
dual-input LO selectable switch, and a pair of differential
IF output amplifiers. Integrated on-chip baluns allow for
single-ended RF and LO inputs. The device requires a
nominal LO drive of 0dBm and a typical supply current of
337mA at V
The MAX19993 is pin compatible with the MAX9985/
M A X 1 9 9 8 5 A / M A X 9 9 9 5 / M A X 1 9 9 9 3 A / M A X 1 9 9 9 4 /
MAX19994A/MAX19995/MAX19995A series of 700MHz
to 2200MHz mixers and pin similar to the MAX19997A/
MAX19999 series of 1850MHz to 4000MHz mixers,
making this entire family of downconverters ideal for
applications where a common PCB layout is used across
multiple frequency bands.
The device is available in a 6mm x 6mm, 36-pin TQFN
package with an exposed pad. Electrical performance is
guaranteed over the extended temperature range, from
