19-5197; Rev 0; 4/10
Dual, SiGe, High-Linearity, 1200MHz to 2000MHz
Downconversion Mixer with LO Buffer/Switch
General Description
The MAX19994A dual-channel downconverter is
designed to provide 8.4dB of conversion gain, +25dBm
input IP3, +14dBm 1dB input compression point, and a
noise figure of 9.8dB for 1200MHz to 2000MHz diversity
receiver applications. With an optimized LO frequency
range of 1450MHz to 2050MHz, this mixer supports both
high- and low-side LO injection architectures for the
1200MHz to 1700MHz and 1700MHz to 2000MHz RF
bands, respectively.
In addition to offering excellent linearity and noise perfor-
mance, the device 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 MAX19994A requires a
nominal LO drive of 0dBm and a typical supply current of
330mA at V CC = 5.0V, or 264mA at V CC = 3.3V.
The MAX19994A is pin compatible with the MAX9985/
MAX9995/MAX19985A/MAX19993/MAX19995/
MAX19995A series of 700MHz to 2500MHz mixers
and pin similar with 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 thin QFN
package with an exposed pad. Electrical performance is
guaranteed over the extended temperature range, from
T C = -40 N C to +85 N C.
