General Description
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.
