Dual Ultra Low Noise, High IP3 Amplifier

The CGY2170HV is an extremely low noise figure cascade amplifier with state of the art noise figure and linearity suitable for applications from 0.5 to 6 GHz. This device consists of two identical amplifiers on the same MMIC, and is ideal for use in a balanced configuration or as two single ended amplifiers. Used as a balanced amplifier with 3 dB couplers, a 0.63 dB noise figure, 34 dBm output IP3 and 23.5 dB gain is obtained at 1.9 GHz. At 3.5 GHz a balanced demonstrator exhibits 0.85 dB noise figure, 19.5 dB gain and OIP3 of 37 dBm. These are measured values and include the noise contribution of the couplers, connectors and biasing circuitry. Extremely low noise, high gain and high IP3 results have been achieved on several demonstrators. The minimum noise figure of itself is 0.32 dB at 1.9 GHz. The MMIC is manufactured using a qualified 0.25 ?m pHEMT GaAs MMIC technology. The device is available in a 4 mm QFN plastic package.
