| MH203A Product Features * * * * * * * +34 dBm Input IP3 7.3 dB Conversion Loss RF: 800 - 960 MHz LO: 1000 - 1310 MHz IF: 70 - 350 MHz +17 dBm Drive Level Lead-free / RoHS-compliant / Green SOIC-8 package * No External Bias Required The Communications Edge TM Product Information High Linearity Cellular-Band MMIC Mixer Product Description 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.

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 f = 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.
