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.
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.

1. Test conditions unless otherwise noted: 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.
