The MH204 is a passive GaAs MESFET mixer that
provides high dynamic range performance in a low
cost SOIC-8 package. WJ’s MH204 uses patented
techniques to realize greater than +30 dBm Input
IP3 at an LO drive level of +17 dBm when used in a
simple application circuit as an upconverting or
downconverting 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 and GSM frequency
IF & RF*
* 4 external components (inductors & capacitors)
are required to diplex the signal

LO Drive Level
1. Data was taken using an application board shown on the following page, with a high side LO at +17 dBm in an downconverting application at 25°C.
2. Input IP3 was measured with two tones with an input power of -5 dBm / tone separated by 1 MHz.

3. Operation of this device above any of these parameters may cause permanent damage.
4. Total sum of LO port and RF port power should not to exceed +23 dBm.
All components are of size 0402
