DOCSIS® 3.1 Upstream Amplifier IC
The DMA2318 is a general purpose, low-cost, high-linearity RF amplifier IC. Employing an amplifier die manufactured on an advanced GaAs process, this linear CATV amplifier is a single-ended, ultra-linear amplifier ideal for high data rate broadband systems. Designed for use as an easily cascadable 75 Ω gain block, its gain flatness of better than ±0.25 dB from 5 MHz to 210 MHz combined with an OIP3 at 100 MHz of >+44 dBm, make this part ideal for cable TV and infrastructure IF applications. No baluns are required and the part is available in a small outline, low profile SMT package.
