• No External Bias Required
The MH203A is a passive GaAs MESFET mixer that
provides high dynamic range performance in a low-cost
lead-free/green/RoHS-compliant SOIC-8 package. WJ’s
MH203A uses patented techniques to realize +34 dBm
Input IP3 at an LO drive level of +17 dBm and can be used
for upconverting or downconverting high-side LO
applications. This single monolithic integrated circuit does
not require any external baluns or bias elements.

Typical applications include frequency up/down
conversion, modulation and demodulation for receivers and
transmitters used in 2.5G and 3G GSM/CDMA/wCDMA
mobile infrastructure in the cellular frequency band.

1. Test conditions unless otherwise noted: RF / IF = 803 / 200, 963 / 200, and 963 / 350 MHz with a high-side LO at +17 dBm in a downconverting application at 25 °C.
The diplexer shown on the application circuit is used in the test fixture.
2. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
3. IIP3 is measured with Δf = 1 MHz with RFin = 0 dBm / tone.
4. The return loss is measured after the diplexer which splits the RF and IF signals from the mixer.
5. The minimum LO port return loss is 9 dB for LO=1000-1064MHz and LO=1089-1310MHz.

Product Information
MH203A-G (Lead-Free/Green SOIC-8 Package) Mechanical Information
This package is lead-free/green/RoHS-compliant. The plating material on the leads is NiPdAu. It is compatible with both lead-free (maximum 260 °C reflow
temperature) and lead (maximum 245 °C reflow temperature) soldering processes.
Product Marking
Outline Drawing
The component will be marked with an
“MH203A-G” designator with an alphanumeric
lot code on the top surface of the package. The
obsolete tin-lead package is marked with an
“M203A” designator with an alpha numeric lot
code.
Tape and reel specifications for this part are
located on the website in the “Application
Notes” section.
