Specifications
Parameters¹
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
bands.
