DOCSIS®4.0 Upstream Amplifier

The DMA2330 is a high-linearity RF amplifier IC designed for exceptionally wide bandwidth (BW), flat gain over BW, and artifact-fee amplification of multi-carrier modulated signals. 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 ±1 dB from 5 MHz to 684 MHz combined with an OIP2 at 500 MHz of >+60 dBm, make this part ideal for upstream Extended Spectrum DOCSIS® and FDX transmitter applications. No baluns are required and the part is available in a no exposed leads, small outline, low profile SMT package.
