Specifications
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.
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.
Absolute Maximum Rating
Operation of this device above any of these parameters may cause permanent damage.

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