Product Information
1.7–2.2 GHz High IP3 Mixer with Integrated LO Amp
Product Description
The ML401 high linearity upconverter or downconverter
combines a passive GaAs MESFET mixer with an
integrated HBT LO driver in a low-cost lead-
free/green/RoHS-compliant SOIC-8 package.
WJ’s
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. The on-chip
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 applications include frequency up/down
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.

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.
IIP3 is measured with
Δf
= 1 MHz with RF
in
= 0 dBm / tone.
LO is injected with 0 dBm.
This refers to the operating current under LO drive. The current can be reduced by increasing the value of the R2 resistor slightly.
