Product Description
Functional Diagram
The MH101 is a passive GaAs MESFET mixer that
provides high dynamic range performance in a low cost
SOIC-8 package. WJ’s MH101 uses patented tech-
niques to realize greater than +30 dBm Input IP3 at an
LO drive level of +17 dBm.
• +30 dBm Input IP3

• No External Matching Elements
Required
• RF 1900-2200 MHz
• LO 1700-2150 MHz
• IF 50-200 MHz
• +17 dBm Drive Level
• Low Cost SOIC-8 Package
• No External Bias Required
This single monolithic integrated circuit does not
require any external baluns, bias, matching, or decou-
pling elements. The on-chip diplexer affords good
matching on the RF and IF ports.
Typical applications include frequency up/down conver-
sion, modulation and demodulation for receivers and
transmitters used in 3G UMTS systems.

Test conditions unless otherwise noted: RF / IF = 1900 / 50, 1900 / 200, 2200 / 50 and 2200 / 200 MHz with a low-side LO at +17 dBm in a downconverting application at 25°C.
Input IP3 was measured with two tones with an input power of +2 dBm/tone separated by 10 MHz.
