General Description
The ML483 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 0.7-1.0 GHz frequency range to achieve +36 dBm Input
IP3 while drawing a very low 50mA current. The ML483
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 ISM and fixed wireless applications.
The ML483 is footprint and pin compatible with TriQuint’s
1.6-3.2 GHz ML485 mixer for high band applications.
