General Description

Pin Configuration

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.
