Introduction

The MAX9996 high-linearity downconversion mixer provides 8.3dB gain, +26.5dBm IIP3, and 9.7dB NF for 1700MHz to 2200MHz UMTS/WCDMA, DCS, and PCS base-station receiver applications. With a 1900MHz to 2400MHz LO frequency range, this particular mixer is ideal for high-side LO injection receiver architectures. Low-side LO injection is supported by the MAX9994, which is pin-for-pin and functionally compatible with the MAX9996. In addition to offering excellent linearity and noise performance, the MAX9996 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 MAX9996 requires a nominal LO drive of 0dBm, and supply current is guaranteed to be below 240mA. 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 MAX9996 is also functionally compatible with the MAX9993. The MAX9996 is available in a compact, 20-pin, thin QFN package (5mm×5mm) with an exposed paddle. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
