The heterojunction increases breakdown voltage and minimizes leakage current between junctions. A Darlington configuration is utilized for broadband performance. The RFCA18 contains two amplifiers for use in wideband push-pull CATV amplifiers requiring excellent second order performance; the second and third order non-linearities are greatly improved in the push-pull configuration. 8 7 6 5 Ordering Information RFCA18SQ 25 Piece sample bag RFCA18SR 7 Sample reel with 1 pieces RFCA18TR13 13 Reel with 25 pieces RFCA18PCK-41 5MHz to 1MHz, PCBA with 5-piece sample bag Optimum Technology Matching Applied GaAs HBT GaAs MESFET InGaP HBT SiGe BiCMOS Si BiCMOS SiGe HBT GaAs phemt Si CMOS Si BJT GaN HEMT BiFET HBT SOI RF MICRO DEVICES, RFMD, Optimum Technology Matching, Enabling Wireless Connectivity, PowerStar, POLARIS TOTAL RADIO and UltimateBlue are trademarks of RFMD, LLC.
