Introduction

The MAX9985 high-linearity, dual-channel downconversion mixer is designed to provide approximately 6dB gain, +28.5 dBm of IIP3, and 10.5dB of noise figure (NF) ideal for diversity receiver applications. With a 700MHz to 1000MHz RF frequency range and a 570MHz to 865MHz LO frequency range, this mixer is ideal for lowside LO injection architectures. In addition, the broad frequency range makes the MAX9985 ideal for GSM 850/950, 2G/2.5G EDGE, WCDMA, cdma2000, and iDEN base-station applications.
