MAX9986:SiGe High-Linearity, 815MHz to 995MHz Downconversion Mixer with LO Buffer/Switch

Lowest Noise, Highest Linearity 1GHz SiGe Mixer for 2.5G and 3G Base Stations

The MAX9986 high-linearity downconversion mixer provides 10dB gain, +23.6dBm IIP3, and 9.3dB NF for 815MHz to 995MHz base-station receiver applications. With a 960MHz to 1180MHz LO frequency range, this particular mixer is ideal for high-side LO injection receiver architectures. Low-side LO injection is supported by the MAX9984, which is pin-for-pin and functionally compatible with the MAX9986. In addition to offering excellent linearity and noise performance, the MAX9986 also yields a high level of component integration. This device includes a double-balanced passive mixer core, an IF amplifier, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also integrated to allow for single-ended RF and LO inputs. The MAX9986 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 265mA. The MAX9984/MAX9986 are pin compatible with the MAX9994/MAX9996 1700MHz to 2200MHz mixers, making this entire family of downconverters ideal for applications where a common PC board layout is used for both frequency bands. The MAX9986 is also functionally compatible with the MAX9993. The MAX9986 is available in a compact, 20-pin, thin QFN package (5mm x 5mm) with an exposed paddle. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
