The RFCM3316 is a power doubler amplifier in a multi-chip module to support the requirements of the new data over cable service interface specification (DOCSIS) 3.1. based on RFMDs GaN and allows cable operators and MSOs to easily upgrade existing CATV infrastructure to meet the power amplifier requirements of the new DOCSIS 3.1 standard, increasing effective downstream data rates from 160 Megabits per second (Mb/s) to 10 Gigabits per second (Gbit/s), and upstream data rates from 120 Mb/s to 1 Gbit/s when compared to DOCSIS 3.0. The RFCM3316 operates from 40MHz to 1200MHz and provides an extremely high output level of 60dBmV under a 1.2GHz channel loading with 10-10 BER and 42dB MER and -80dB CTB and -80dB CSO. This modular, surface mount device saves about 50 percent in board space compared to traditional SOT115J packages, while maintaining excellent linearity and ruggedness. Due to the efficient nature of the GaN process, the product can also operate at 20% less current than Gallium Arsenide-based products at a comparable distortion level.
