The MH203 is a passive GaAs MESFET mixer that provides high dynamic range performance in a low cost SOIC-8 package. WJ's MH203 uses patented techniques to realize +32 dBm Input IP3 at an LO drive level of +17 dBm when used in a simple application circuit as an upconverting or downconverting high-side LO configuration. 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 systems using the cellular and GSM frequency bands.
