The CGY2105XHV/C1 is an extremely Low Noise Figure Dual Amplifier with state-of-the-art Noise Figure and Linearity suitable for applications from 500 MHz to 4 000 MHz.
The CGY2105XHV/C1 consists of two identical amplifiers on the same MMIC and is ideal for use in a balanced configuration. Extremely low noise, high gain, and high IP3 results have been achieved on several demonstrators. The minimum Noise Figure of the CGY2105XHV itself is 0.23 dB at 1.9 GHz.
The MMIC is manufactured using OMMIC’s qualified 0.13 µm PHEMT GaAs D01PH technology. The D01PH process is one of the European Space Agency (ESA) European preferred part list (EPPL) technologies. The device is available in a 4×4 mm QFN plastic package.
