The CGY2181UH/C1 is a high performance GaAs based Double Balanced Mixer MMIC with on chip RF and LO baluns. The CGY2181UH covers the frequency range of 1 GHz to 4.5 GHz with a conversion loss of typically 7 dB. On-chip baluns provide excellent rejection of LO to RF and IF paths. High dynamic range is provided by the passive mixer configuration. This device can be used in GPS, Telecommunication, Radar, EW and Instrumentation applications.

The die is manufactured using OMMIC’s 0.18 μm gate length PHEMT Technology. The MMIC uses gold bonding pads and backside metallization and is fully protected with Silicon Nitride passivation to obtain the highest level of reliability. This technology has been evaluated for Space applications and is on the European Preferred Parts List of the European Space Agency.
