Qorvo has added ten new DOCSIS 3.1-ready reverse path amplifiers to its portfolio, enabling cable broadband service providers with the fastest data rate capabilities required for high-bandwidth content uploading. These reverse path products equip cable providers with next-generation technology that is 'future-proof,' offering faster upstream data rate capability than the standard set forth by the current phase of DOCSIS 3.1. Cable operators utilizing fiber to the home (FTTH) and hybrid fiber coaxial (HFC) networks will now be able to provide higher bandwidth to meet the increasing subscriber demand for upstream and interactive content.
Qorvo's new products for HFC and FTTH applications include the RFCA8830 and RFCA1008 reverse path power amplifiers capable of operating up to 300 MHz – well beyond the current return path requirement of 204 MHz. The newly released RFCM5304 includes integrated functionality such as power down, adjustable gain control (AGC), configurable current, first stage amplifier bypass, and an on-chip thermal pin to sense IC temperature during operation.
The reverse path amplifiers are available in standard HFC; SOT-115J form factor; miniaturized multi-chip module (MCM); and monolithic microwave integrated circuit (MMIC) packages, including QFN and SOIC. These products accelerate the deployment of high-speed CATV DOCSIS 3.1 networks while providing cable designers greater flexibility in product design.
Qorvo offers a large range of DOCSIS 3.1-ready products, with more than 60 components including pre-driver gain blocks and push-pull and power doubler amplifiers employing the latest high-performance process technologies, including GaN high-electron-mobility transistor (HEMT), which delivers superior linearity, output power and reliability. Qorvo's forward path amplifiers operate from 45 MHz to 1.2 GHz with very high output (capable of 76 dBmV composite power), extremely low distortion (lower than 70 dBc), and excellent input and output return loss (-20 dB typical).
They plan to showcase these products and the DOCSIS 3.1 portfolio at the upcoming China Content Broadcasting Network (CCBN) Exhibition in Beijing, China, March 24-26, 2016 at booth 2501.
