The CGY2175AHV/C1 is a high performance QFN packaged 3 port, 6-bit Core Chip operating in Cband. It includes a 6-bit phase shifter, a 6-bit attenuator and a T/R switch. The Serial 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. This technology has been evaluated for Space applications and is on the European Preferred Parts List of the European Space Agency.

The device is available in a 7*7 mm QFN package.
