Specifications
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 RF
Absolute Maximum Rating
Operation of this device above any of these parameters may cause permanent damage.

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.
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.
Typical
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.
