Product Features

Applications

Specifications

Test conditions unless otherwise noted:

1. Performance is with the use of an application specific circuit (shown on page 4) with a high-side LO at +17 dBm in a downconverting application at 25° C.

2. Assumes LO injection noise is filtered at the thermal noise floor, -174 dBm/Hz, at the RF, IF, and Image frequencies.

3. IIP3 is measured with f = 1 MHz with RF

4. The return loss is measured after the diplexer which splits the RF and IF signals from the mixer. Details of the diplexing circuit is shown on page 4.

Absolute Maximum Rating

5. Operation of this device above any of these parameters may cause permanent damage.

6. Total sum of the LO and RF port power should not exceed +23 dBm.

The MH203 is a passive GaAs MESFET mixer that

provides high dynamic range performance in a low

cost SOIC-8 package. WJ’s MH203 uses patented

techniques to realize +32 dBm Input IP3 at an LO

drive level of +17 dBm when used in a simple

application

downconverting high-side LO configuration.

single monolithic integrated circuit does not require

any external baluns or bias elements.

Typical applications include frequency up/down

conversion,

receivers and transmitters used in 2.5G and 3G

systems using the cellular and GSM frequency bands.
