The CGY2175BUH/C1 is a high performance GaAs MMIC 4-port, 6–bit Core Chip operating in C-band. It includes a 6-bit phase shifter, a 6-bit attenuator and T/R switch. The on-chip Series to Parallel Converter minimizes the number of bonding pads and greatly simplifies the use of the Core Chip functions.

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
