MH1A
High Dynamic Range PCS-Band MMIC Mixer
The Communications Edge TM
Product Information
Product Features
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.

Product Marking
The component will be marked with an
“MH1AG” designator followed by an
alphanumeric lot code on the top surface of the
package. The obsolete tin-lead package is
marked with an “MH1A” designator followed by
an alphanumeric lot code.
Tape and reel specifications for this part are
located on the website in the “Application Notes”
section.
