MMIC Amplifiers Target Microwave/Millimeterwave Radios
Hittite Microwave’s HMC451LP3E and HMC-ABH264 GaAs PHEMT MMIC amplifiers work in point-to-point and point-to-multipoint radios, as well as VSAT, military and space, fiber optics, sensor, and test instrumentation applications. The RoHS-compliant HMC451LP3E operates from 5 GHz to 18 GHz with 18-dB gain, 21-dBm saturated output power at 18% PAE, and 28-dBm output IP3 in a temperature range from -40°C to 85°C. The HMC-ABH264 performs from 34 GHz to 42 GHz with 18.5-dB gain, 18-dBm P1dB, and 29-dBm output IP3 in a temperature range from -55°C to 85°C. The medium power amplifiers exhibit power consumption of 120 mA from a 5-V supply, DC blocked I/Os, and 50-Ω matched.
