MAX9993

19-2596; Rev 0; 10/02 High-Linearity 1700MHz to 2200MHz DownConversion Mixer with LO Buffer/Switch General Description The MAX9993 high-linearity down-conversion mixer provides 8.5dB of gain, +23.5dBm IIP3, and 9.5dB NF for UMTS, DCS, and PCS base-station applications. The MAX9993 integrates baluns in the RF and LO ports, a dual-input LO selectable switch, an LO buffer, a double-balanced mixer, and a differential IF output amplifier. The MAX9993 requires a typical LO drive of +3dBm, and supply current is guaranteed to below 230mA. The MAX9993 is available in a compact 20-pin thin QFN package (5mm ✕ 5mm) with an exposed pad. Electrical performance is guaranteed over the extended -40°C to +85°C temperature range. The MAX9993 EV kit is available; contact the factory for more information. o +23.5dBm Input IIP3 o 1700MHz to 2200MHz RF Frequency Range o 40MHz to 350MHz IF Frequency Range o 1400MHz to 2000MHz LO Frequency Range o 8.5dB Conversion Gain o 9.5dB Noise Figure o Integrated LO Buffer o Switch-Selectable (SPDT), Two LO Inputs o Low 0 to +6dBm LO Drive o 40dB LO1-to-LO2 Isolation Features MAX9993 Applications UMTS and 3G Base Stations DCS1800 and EDGE Base Stations PCS1900 Base Stations Point-to-Point Microwave Systems Wireless Local Loop Private Mobile Radio Military Systems PART MAX9993ETP-T Ordering Information TEMP RANGE -40°C to 85°C PIN-PACKAGE 20 Thin QFN-EP* *EP = Exposed pad.
