Product Description
Functional Diagram
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.
• +34 dBm IIP3
• RF: 1900 – 2700 MHz

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.

1. Specifications are guaranteed at: RF / IF = 1900 / 50, 1900 / 200, 2200 / 50, and 2200 / 300 MHz with a low-side LO at +17 dBm in a downconverting application at 25 °C.
2. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.
3. IIP3 is measured with Δf = 1 MHz with RFin = 0 dBm / tone.
