The MAX9994 high-linearity downconversion mixer provides 8.3dB gain, +26.2dBm IIP3, and 9.7dB NF for 1400MHz to 2200MHz UMTS/WCDMA, DCS, and PCS base-station receiver applications. With a wide LO range of 1400MHz to 2000MHz, the MAX9994 can be used in either high-side or low-side LO injection architectures, depending on the RF band of interest. Higher LO applications are supported by the MAX9996, which is pin-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. 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 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 pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range.
