ML485

ML485 1.6–3.2 GHz High IP3 Mixer with Integrated LO Amp Product Features • High dynamic range mixer with integrated LO driver • +35 dBm Input IP3 • 8 dB Conversion Loss • RF: 1600 – 3200 MHz • LO: 1400 – 3500 MHz • IF: 50 – 300 MHz • 5V Supply @ 40 mA • 0 dBm Drive Level • RoHS-compliant MSOP8 (14mm2) Product Description The ML485 high linearity converter combines a passive GaAsFET mixer with an integrated LO driver in an ultrasmall lead-free/green/RoHS-compliant MSOP-8 package. The High dynamic range mixer is able to operate across a wide 1.6-3.2 GHz frequency range to achieve +35 dBm Input IP3 while drawing a very low 40mA current. The ML485 can be used as an upconverter or downconverter in a low-side or high-side LO configuration. A LO buffer amplifier is integrated on the chip to allow for operation directly from a synthesizer, requiring only 0 dBm of drive level. The dual-stage LO driver provides a stable input power level into the mixer to allow for consistent performance over a wide range of LO power levels. The converter requires no external baluns and supports a wide range of IF frequencies. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in 2.5G and 3G mobile infrastructure. Due to the wide frequency range of operation, the converter can also be used for WiMAX, WiBro, ISM, and fixed wireless applications.
