Specifications
1. Min / max limits are tested for the mixer in downconverting application with a low-side LO at 0 dBm at 25 °C with RF/IF = 1800/50, 2000/50, and 1800/200 MHz.
2. IIP3 is measured with Δf = 1 MHz with RF
3. LO is injected with 0 dBm.
4. This refers to the operating current under LO drive. The current can be reduced by increasing the value of the R2 resistor slightly.
Absolute Maximum Rating
Operation of this device above any of these parameters may cause permanent damage.

The ML401 high linearity upconverter or downconverter
combines a passive GaAs MESFET mixer with an
integrated
free/green/RoHS-compliant SOIC-8
ML401 uses patented techniques to realize +31 dBm Input
IP3 with 8 dB conversion loss using an LO drive level of 0
dBm in a downconverting application.
diplexer in the mixers allows for good matching on the RF
and IF ports. 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.
Typical
conversion, modulation and demodulation for receivers and
transmitters used in 2.5G and 3G GSM/CDMA/W-CDMA
systems in the DCS, PCS, or UMTS frequency bands.
