MAX19993

Dual, SiGe, High-Linearity, 1200MHz to 1700MHz

Downconversion Mixer with LO Buffer/Switch

19-5307; Rev 0; 6/10

General Description

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

= +5.0V or 275mA at V

= +3.3V.

The MAX19993 is pin compatible with the MAX9985/

MAX1 9985A/M AX 9995/ MA X19993A /MAX199 94/

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

= -40NC to +85NC.
