19-0705 Rev 0; 1/07 EVALUATION KIT AVAILABLE Dual, SiGe, High-Linearity, 700MHz to 1000MHz Downconversion Mixer with LO Buffer/Switch MAX9985 General Description Features The MAX9985 high-linearity, dual-channel downconver- 700MHz to 1000MHz RF Frequency Range sion mixer is designed to provide approximately 6dB 570MHz to 865MHz LO Frequency Range gain, +28.5dBm of IIP3, and 10.5dB of noise figure (NF)ideal for diversity receiver applications. With a 700MHz 50MHz to 250MHz IF Frequency Range to 1000MHz RF frequency range and a 570MHz to 6dB Typical Conversion Gain 865MHz LO frequency range, this mixer is ideal for low-side LO injection architectures. In addition, the broad 10.5dB Typical Noise Figure frequency range makes the MAX9985 ideal for GSM +28.5dBm Typical Input IP3 850/950, 2G/2.5G EDGE, WCDMA, cdma2000®, and +16.2dBm Typical Input 1dB Compression Point iDEN® base-station applications. 77dBc Typical 2RF-2LO Spurious Rejection at The MAX9985 dual-channel downconverter achieves a P high level of component integration. The MAX9985 inte- RF = -10dBm grates two double-balanced active mixer cores, two LO Dual Channels Ideal for Diversity Receiver buffers, a dual-input LO selectable switch, and a pair of Applications differential IF output amplifiers. In addition, integrated 47dB Typical Channel-to-Channel Isolation on-chip baluns at the RF and LO ports allow for single-ended RF and single-ended LO inputs. The MAX9985 -3dBm to +3dBm LO Drive requires a typical 0dBm LO drive. Supply current is Integrated LO Buffer adjustable up to 400mA. Internal RF and LO Baluns for Single-Ended The MAX9985 is available in a 36-pin thin QFN pack- Inputs age (6mm x 6mm) with an exposed paddle. Electricalperformance is guaranteed over the extended tempera- Built-In SPDT LO Switch with 43dB LO1-to-LO2 ture range, from T Isolation and 50ns Switching Time C = -40°C to +85°C. Pin-Compatible with MAX9995/MAX9995A Applications 1700MHz to 2200MHz Mixers 850MHz WCDMA Base Stations Lead-Free Package Available GSM 850/GSM 950, 2G/2.5G EDGE BaseStations Ordering Information cdmaOneTM and cdma2000 Base Stations
