Product Description
Functional Diagram
The MH102 is a passive GaAs MESFET mixer that
provides high dynamic range performance in a low
cost SOIC-8 package. WJ’s MH102 uses patented
techniques to realize greater than +30 dBm Input
IP3 at an LO drive level of +17 dBm.

• RF 1900-2200 MHz
• IF 150-300 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.
Typical applications include frequency up/down con-
version, modulation and demodulation for receivers
and transmitters used in 3G UMTS systems.

Test conditions unless otherwise noted: RF / IF = 1900 / 300, 2200 / 150, and 2200 / 300 MHz with a low-side LO at +17 dBm in a downconvertering applicaion at 25°C.
Input IP3 was measured with two tones with an input power of +2 dBm/tone separated by 10 MHz.
