SiGe High-Linearity, 2000MHz to 3000MHz
Upconversion/Downconversion Mixer with LO Buffer
MAX2042
General Description
The MAX2042 single, high-linearity upconversion/down-
conversion mixer provides +36dBm IIP3, 7.3dB noise fig-
ure, and 7.2dB conversion loss for 2000MHz to 3000MHz
WCS, LTE, WiMAXK, and MMDS wireless infrastructure
applications. With a wide LO frequency range of 1800MHz
to 2800MHz, this particular mixer is ideal for low-side LO
injection receiver and transmitter architectures. High-side
LO injection is supported by the MAX2042A, which is pin-
pin and functionally compatible with the MAX2042.
In addition to offering excellent linearity and noise
performance, the MAX2042 also yields a high level of
component integration. This device includes a double-
balanced passive mixer core, an LO buffer, and on-chip
baluns that allow for single-ended RF and LO inputs.
The MAX2042 requires a nominal LO drive of 0dBm,
and supply current is typically 138mA at V
CC = +5.0V or
120mA at V CC = +3.3V.
The MAX2042 is pin compatible with the MAX2042A
2000MHz to 3900MHz mixer. The device is also pin simi-
lar with the MAX2029/MAX2031 650MHz to 1000MHz
mixers, the MAX2039/MAX2041 1700MHz to 3000MHz
mixers, and the MAX2044/MAX2044A 3000MHz to
4000MHz mixers, making this entire family of up/down-
converters ideal for applications where a common PCB
layout is used for multiple frequency bands.
The MAX2042 is available in a compact 20-pin thin QFN
(5mm x 5mm) package with an exposed pad. Electrical
performance is guaranteed over the extended -40NC to
+85NC temperature range.
