The MH202 is a passive GaAs MESFET mixer that
provides high dynamic range performance in a low
cost SOIC-8 package. WJ’s MH202 uses patented
techniques to realize +30 dBm Input IP3 at an LO
drive level of +17 dBm when used in a simple
application circuit as an upconverting configuration.
This single monolithic integrated circuit does not
require any external baluns or bias elements.
Typical applications include frequency up/down
conversion, modulation and demodulation for
receivers and transmitters used in 2.5G and 3G
systems using the cellular GSM frequency band.
