General Description
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 1.5 – 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 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
