The MH205A 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
MH205A uses patented techniques to realize +35 dBm
Input IP3 at an LO drive level of +17 dBm and can be used
for upconverting or downconverting low-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 / 70 and 963 / 70 with a low-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.
