Product Features
Specifications
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.
Absolute Maximum Ratings
1. Operation of this device above any of these parameters may cause permanent damage.
2. Total sum of LO port and RF port power should not to exceed +23 dBm.

Product Description
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.
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.
