Qorvo's ML485-G high linearity converter combines a passive GaAs FET mixer with an integrated LO driver in an ultra-small lead-free / green / RoHS-compliant MSOP-8 package. The double-balanced integrated IC is able to operate across a wide 1.5 - 3.2 GHz frequency range to achieve +35 dBm Input IP3 while drawing a very low 40 mA current. The ML485-G can be used as an up-converter or down-converter 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 LO 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, LTE and fixed wireless applications
