The MH203A 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 MH203A 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 high-side LO applications. This single monolithic integrated circuit does not require any external baluns or bias elements.
