The CGY2121XUH/C2 is a high-performance GaAs Low Noise Amplifier MMIC designed to operate in the K band.

The CGY2121XUH/C2 has an exceptionally low noise figure of 1.2 dB with a very flat 19 dB of gain (+/-0.4dB). The on chip matching provides 12 dB of Input Return Loss and 11 dB of Output Return Loss. Thanks to the DC regulation the gain and noise are very stable wrt temperature change. It can be used in Radar, Telecommunication, and Instrumentation applications.

The die is manufactured using OMMIC’s Advanced 70 nm gate length high Indium content MHEMT Technology. The MMIC uses gold bonding pads and backside metallization and is fully protected with Silicon Nitride passivation to obtain the highest level of reliability.

Application Schematic

To prevent unstability of the customer design it is highly recommended to place small chip capacitors as near as possible to the CGY2121XUH/C2 die and to connect them with bondings as short as possible.

Additionally, a 10nF capacitor can be added on a drain connection. In the gate circuitry, a 500 Ω resistor may be added in serie to improve gate isolation and prevent unwanted oscillations. The resistors are introducing some low pass filtering in case of fast power switching using gate control architecture.
