4-Bit, Ku-Band Core Chip

The CGY2179UH/C1 is a high performance 4-bit Core Chip operating in Ku-band. It includes a 4-bit phase shifter and a LNA. It has a phase shifting range of 360°, and a LSB of 22.5°. It covers the frequency range from 10.7 to 12.75 GHz. 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 0.18 μm gate length pHEMT Technology ED02AH. The MMIC uses gold bond 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.
