Push-Pull CATV Amplifier

www.DataSheet4U.com AG606 The Communications Edge TM Product Information Push-Pull CATV Amplifier Product Features x x x x x x 50 – 860 MHz ±0.7 dB Gain Flatness +20 dBm P1dB +37 dBm Output IP3 +73 dBm Output IP2 -68 dBc CTB Product Description The AG606 is a dual amplifier containing two internal matched amplifiers optimal for a push-pull configuration. The internal amplifiers employ InGaP HBT technology for a cost-effective low-distortion solution. The AG606 is ideal for drop amplifiers, splitters, and other low to moderate power outside plant CATV applications. The amplifier can also be useful in low power headend applications such as linear laser drivers. The AG606 has excellent VSWR when used in a 75 : push-pull configuration. It is provided in a low-cost environmentally-friendly lead-free/green/RoHS-compliant SOIC-8 package.
