Dual, SiGe, High-Linearity, 1200MHz to 1700MHz  
Downconversion Mixer with LO Buffer/Switch  
General Description  
Features  
Sꢀ 1200MHz_to_1700MHz_RF_Frequency_Range  
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  
P _=_-10dBm

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.
