The CGY2351UH/C1 is a high performance GaAs MMIC Core Chip operating in Ka-band. It follows the T/R architecture, is passive, and exhibits only 2 RF ports. It includes a 6 bit Phase shifter and a 5 bits attenuator; it has a phase shift range of 360° with a 5.62° step and attenuation range of 22 dB with 0.7 dB step. It operate from 26.5 to 30.5 GHz. The on-chip control logic with serial input register minimizes the number of bonding pads and greatly simplifies the interface with this device.
The die is manufactured using ED02AH OMMIC’s 180 nm gate length pHEMT technology. The MMIC uses gold bonding pads and backside metallization. It is fully protected by a Silicon Nitride passivation layer to obtain the highest level of reliability. This technology has been evaluated for space applications by the European Space Agency (ESA) and is on the European Preferred Parts List of ESA.
