Maxim Integrated MAX9994
The MAX9994 high-linearity downconversion mixer provides 8.3dB gain, +26.2dBm IIP3, and 9.7dB NF for 1700MHz to 2200MHz UMTS/WCDMA, DCS, and PCS base-station receiver applications. With a 1400MHz to 2000MHz LO frequency range, this particular mixer is ideal for low-side LO injection receiver architectures. This device includes a doublebalanced passive mixer core, an IF amplifier, a dualinput LO selectable switch, and an LO buffer.

GENERAL DESCRIPTION
High-side LO injection is supported by the MAX9996*, which is pin-for-pin and functionally compatible with the MAX9994. In addition to offering excellent linearity and noise performance, the MAX9994 also yields a high level of component integration. On-chip baluns are also integrated to allow for single-ended RF and LO inputs. The MAX9994 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 235mA. The MAX9994/MAX9996 are pin compatible with the MAX9984/MAX9986 815MHz to 995MHz mixers, making this entire family of downconverters ideal for applications where a common PC board layout is used for both frequency bands. The MAX9994 is also functionally compatible with the MAX9993. The MAX9994 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. FEATURES
