Product Description

The MH103A 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

MH103A uses patented techniques to realize +34 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

applications

include

frequency

up/down

conversion, modulation and demodulation for receivers and

transmitters used in 3G UMTS systems.
