The CMD177 is a general purpose double

balanced mixer die that can be used for up- and

downconverting applications between 6 and 14

GHz. The CMD177 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 +9 dBm. The CMD177

can easily be configured as an image reject

mixer or single sideband modulator with

external hybrids and power splitters.

► Low conversion loss

► High isolation

► Wide IF bandwidth

► Passive double balanced topology

► Small die size
