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 applications.
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 performance,
the MAX19996 also yields a high level of component
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 singleended
RF and LO inputs. The MAX19996 requires a
nominal LO drive of 0dBm, and supply current is typically
230mA at VCC = +5.0V or 149.5mA at VCC = +3.3V.
The MAX19996 is pin compatible with the MAX19996A
2300MHz to 3900MHz mixer. The device is also pin similar
with the MAX9984/MAX9986 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 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.
