The ML485 high linearity converter combines a passive
GaAsFET 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 1.6-3.2 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
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.
