Features - - - - - - The munications Edge TM Product Information High Dynamic Range PCS-Band MMIC Mixer Product Description The MH1A is a passive Ga As MESFET mixer that provides high dynamic range performance in a low-cost lead-free/green/Ro HS-pliant SOIC-8 package. WJ’s MH1A uses patented techniques to realize +35 d Bm Input IP3 at an LO drive level of +17 d Bm 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 2.5G and 3G GSM/CDMA /w CDMA systems in the DCS, PCS, or UMTS frequency bands.
