The HMC474SC70(E), HMC476SC70(E), HMC311SC70(E) and HMC478SC70(E) are a family of SiGe and GaAs Heterojunction Bipolar Transistor (HBT) Gain Block SMT MMIC amplifiers covering DC to 8 GHz. These cascadable amplifiers deliver up to 23 dB gain, +17 dBm output P1dB and +30 dBm output IP3, with noise figure as low as 2.5 dB. The amplifiers operate from a single positive supply as low as +3V, consume between 25 and 64 mA of current, and maintain excellent stability over temperature while requiring a minimal number of external components. The HMC474SC70(E), HMC476SC70(E), HMC311SC70(E) and HMC478SC70(E) MMIC Gain Block amplifiers are ideal for use in IF, RF, and PA pre-driver applications in Automotive, CATV, Cellular/3G, WiBro, WiMAX, and Fixed Wireless systems. These versatile gain blocks require no external matching components and are housed in industry standard and RoHS compliant SC70 ā€œEā€ SMT packages, which occupy a PCB footprint of only 2x2 mm.
