The MH102 is a passive GaAs MESFET mixer that provides high dynamic range performance in a low cost SOIC-8 package. WJ's MH102 uses patented techniques to realize +32 dBm Input IP3 at an LO drive level of +17 dBm. This single monolithic integrated circuit does not require any external baluns, bias, matching, or decoupling elements. The on-chip diplexer affords good matching on the RF and IF ports. Typical applications include frequency up/ down conversion, modulation and demodulation for receivers and transmitters used in 3G UMTS or 1930-1990 MHz PCS band mobile infrastructure.
