General Description
The MAX19996 single, high-linearity downconversion
mixer provides 8.7dB conversion gain, +24.5dBm IIP3,
and 9.6dB noise figure for 2000MHz to 3000MHz WCS,
LTE, WiMAX™, and MMDS wireless infrastructure appli-
cations. With an 1800MHz to 2550MHz LO frequency
range, this particular mixer is ideal for low-side LO
injection receiver architectures. High-side LO injection
is supported by the MAX19996A, which is pin-for-pin
and functionally compatible with the MAX19996.
In addition to offering excellent linearity and noise perfor-
mance, the MAX19996 also yields a high level of compo-
nent integration. This device includes a double-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 MAX19996 requires a
nominal LO drive of 0dBm, and supply current is typical-
ly 230mA at V
CC
= +5.0V or 149.5mA at V
CC
= +3.3V.
The MAX19996 is pin compatible with the MAX19996A
2300MHz to 3900MHz mixer. The device is also pin sim-
ilar with the MAX9984/MAX9986 400MHz to 1000MHz
mixers and the MAX9993/MAX9994/MAX9996 1700MHz
to 2200MHz mixers, making this entire family of down-
converters ideal for applications where a common PCB
layout is used for multiple frequency bands.
The MAX19996 is available in a compact 5mm x 5mm,
20-pin thin QFN lead-free package with an exposed
pad. Electrical performance is guaranteed over the
extended -40°C to +85°C temperature range.
