The CGY2133UH/C1 is a PHEMT GaAs Power Amplifier with output power of 30dBm (1W) and more than 19dB of gain covering frequencies from 39 to 44 GHz.

The CGY2133UH is a 3 stage dual line-up architecture with lange power couplers for power combining and excellent input and output matching.

The 1dB compression point is 28 dBm with excellent linearity delivering OIP3 at 37 dBm. DC power supply is 4.5V and PAE above 12%.

The CGY2133UH is manufactured using the D01PH GaAs PHEMT power process from OMMIC. This process has a 130nm gate length with a Ft 110Ghz and a Fmax of 180GHz.

The D01PH process used to manufacture the MMIC has been evaluated by ESA and is present in the EPPL (European Preferred Part List). This very reliable process is suitable to manufacture power amplifiers dedicated to flight models in aerospace applications as well as power amplifier for terrestrial applications.
