Features - - - - - - - The munications Edge TM Cellular-band Quad-FET Mixer Product Information Product Description The MH303 is a passive Quad-MOSFET mixer that provides high dynamic range performance in a low cost 3x3 mm 6-pin DFN (Dual Flat No-Lead) leadfree/green/Ro HS-pliant package. WJ’s MH303 uses patented techniques to realize +28 d Bm Input IP3 at an LO drive level of +13 d Bm when used in a simple application circuit with a low-side LO configuration. The LO can also be driven with higher power levels up +20 d Bm to achieve higher IP3 performance. This mixer integrates internal circuitry to provide single-ended interfaces for the RF & LO ports. Typical applications include frequency up/down conversion, modulation and demodulation for receivers and transmitters used in cellular-band 3G mobile infrastructure.
