| ML485 Product Features 1.6-3.2 GHz High IP3 Mixer with Integrated LO Amp 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 double-balanced integrated IC 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 synthesize 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.
