SiGe, High-Linearity, 2000MHz to 3900MHz
Downconversion Mixer with LO Buffer
General Description
The MAX19996A single, high-linearity downconversion
mixer provides 8.7dB conversion gain, +24.5dBm IIP3,
and 9.8dB noise figure for 2000MHz to 3900MHz WCS,
LTE, WiMAX™, and MMDS wireless infrastructure appli-
cations. With an ultra-wide LO frequency range of
2100MHz to 4000MHz, the MAX19996A can be used in
either low-side or high-side LO injection architectures
for virtually all 2.5GHz and 3.5GHz applications. For a
2.5GHz variant tuned specifically for low-side injection,
refer to the MAX19996 data sheet.
In addition to offering excellent linearity and noise
performance, the MAX19996A also yields a high level
of component integration. This device includes a dou-
ble-balanced passive mixer core, an IF amplifier, and
an LO buffer. On-chip baluns are also integrated to
allow for single-ended RF and LO inputs. The
MAX19996A requires a nominal LO drive of 0dBm,
and supply current is typically 230mA at V_CC = 5.0V,
or 150mA at V_CC = 3.3V.
The MAX19996A is pin compatible with the MAX19996
2000MHz to 3000MHz mixer. The device is also pin
similar with the MAX9984/MAX9986/MAX9986A
400MHz to 1000MHz mixers and the MAX9993/
MAX9994/MAX9996 1700MHz to 2200MHz mixers,
making this entire family of downconverters ideal for
applications where a common PCB layout is used for
multiple frequency bands.
The MAX19996A is available in a compact 5mm x 5mm,
20-pin thin QFN with an exposed pad. Electrical perfor-
mance is guaranteed over the extended -40°C to
+85°C temperature range.
