RFIC Solutions Inc. CATV Line Amplifier Description . Preliminary Datasheet RTV01 Functional Diagram Supply Biasing Ckt . The RTV01 is a CATV Line Amplifier IP block. CATV Line Amplifier designed using GaAs Enhancement mode psuedomorphic high electron mobility transistor (pHEMT). The amplifier provides low distortion and noise figure along with flat gain. The part is biased at 8V. This covers the range for 40 to 870 MHz band. The optimized on-chip impedance matching circuitry provides 50 ohm nominal RF input impedance and is provided in a low-cost industrystandard 14 Pin SOIC Package. Applications. · CABLE TV . Matching Matching Key Features. · · · Gain flatness of 2.5 dB Small Size, Low Cost High Performance . Electrical Specifications. .
