| MH103A Product Features * * * * * * +34 dBm IIP3 RF: 1900 - 2700 MHz LO: 1600 - 2650 MHz IF: 50 - 300 MHz +17 dBm Drive Level Lead-free/green/RoHS-compliant SOIC-8 SMT package * No External Bias Required The Communications Edge TM Product Information High Dynamic Range 1.9 - 2.7 GHz MMIC Mixer Product Description The MH103A 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 MH103A 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 low-side LO applications. 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 systems.
