Product Description
Functional Diagram
+35 dBm IIP3
RF: 1700 – 2000 MHz
LO: 1450 – 1950 MHz
IF: 50 – 250 MHz
+17 dBm Drive Level
Lead-free/green/RoHS-compliant
SOIC-8 SMT package
No External Bias Required
The MH1A 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
MH1A uses patented techniques to realize +35 dBm Input
IP3 at an LO drive level of +17 dBm 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.
Applications
2.5G and 3G
GSM/CDMA/wCDMA
Optimized for DCS/PCS-band
Mobile Infrastructure
Typical applications include frequency up/down
conversion, modulation and demodulation for receivers and
transmitters used in 2.5G and 3G GSM/CDMA /wCDMA
systems in the DCS, PCS, or UMTS frequency bands.

RF=1850-1910MHz, IF=235-245MHz, See note 3
All other RF/IF combinations, See note 3
LO = 1450 – 1950 MHz
LO = 2256 – 2321 MHz
Referenced to the nominal LO drive level of 17 dBm
Return loss phase is nominally at -90˚ at 1.9 GHz.
1. Test conditions unless otherwise noted: RF / IF = 1700 / 250, 2000 / 50, and 2000 / 250 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 = 5 dBm / tone.
