The CGY2170XUH/C2 is a high performance GaAs MMIC T/R 6–bit Core Chip operating in X-band. It includes a 6-bit phase shifter, a 6-bit attenuator, and switches. It has a phase shifting range of 360° and a gain setting range of 31.5 dB. It covers the frequency range from 8 to 12 GHz and can be used in Radar, Telecommunication and Instrumentation applications.

The on-chip control logic with serial input register minimizes the number of bonding pads and greatly simplifies the interfacing to this device.

This 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.
