CMD178

11 - 21 GHz Fundamental Mixer

The CMD178 is a general purpose double balanced mixer die that can be used for up- and downconverting applications between 11 and 21 GHz. The CMD178 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 CMD178 can easily be configured as an image reject mixer or single sideband modulator with external hybrids and power splitters.
