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 VCC = 5.0V,
or 150mA at VCC = 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.

Note 1: Based on junction temperature TJ = TC + (θJC x VCC x ICC). This formula can be used when the temperature of the exposed
pad is known while the device is soldered down to a PCB. See the Applications Information section for details. The junction
temperature must not exceed +150°C.
Note 2: Junction temperature TJ = TA + (θJA x VCC x ICC). This formula can be used when the ambient temperature of the PCB is
known. The junction temperature must not exceed +150°C.
Note 3: Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-
layer board. For detailed information on package thermal considerations, refer to www.maxim-ic.com/thermal-tutorial.
Note 4: TC is the temperature on the exposed pad of the package. TA is the ambient temperature of the device and PCB.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
