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 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.
