High-Linearity 1700MHz to 2200MHz Down-Conversion Mixer with LO Buffer/Switch
Lowest Noise, Highest Linearity, 1700MHz to 2200MHz SiGe Downconversion Mixer for Base Stations
DescriptionThe MAX9993 high-linearity down-conversion mixer provides 8.5dB of gain, +23.5dBm IIP3, and 9.5dB noise figure 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 x 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.
