The CMD253C3 is a high IP3 double balanced

mixer in a leadless surface mount package that

can be used for up- and downconverting

applications between 6 and 14 GHz.

The

CMD253C3 has very high isolation to both the

RF and IF ports due to the optimized balun

structures, and can operate with an LO drive

level as low as +15 dBm. The CMD253C3 can

easily be configured as an image reject mixer or

single sideband modulator with external hybrids

and power splitters.

► Low conversion loss
