Product Description
The MH1 is a passive FET mixer that provides
high dynamic range performance in a low cost
SOIC-8 package. WJ’s FET based MH1 uses
patented techniques to realize +30 dBm IIP3 at
an LO drive level of +17 dBm. The product is
fully self contained and does not require any
external bias, matching or decoupling elements.
Typical applications include frequency up/down
conversion, modulation and demodulation for
receivers and transmitters used in PCS,
DCS1800 and PHS systems.
