General Description
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. High-side LO injection is supported by the MAX9996*, which is pin-for-pin and functionally compatible with the MAX9994.
