Qorvo offers maximum upstream bandwidth with new DOCSIS 3.1-ready reverse-path amplifiers

Qorvo Inc of Greensboro, NC and Hillsboro, OR, USA (which provides core technologies and RF solutions for mobile, infrastructure and defense applications) 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.

"Qorvo's 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," says Kellie Chong, director, CATV and Broadband Access products for Qorvo. "Now, cable operators utilizing fiber-to-the-home (FTTH) and hybrid fiber coaxial (HFC) networks can provide higher bandwidth to meet the increasing subscriber demand for upstream and interactive content."

The new products for HFC and FTTH applications include the RFCA8830 and RFCA1008 reverse-path power amplifiers capable of operating up to 300MHz – well beyond the current return-path requirement of 204MHz. 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.

Qorvo's 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, says Qorvo.

Qorvo claims that it offers the most 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 gallium nitride (GaN) high-electron-mobility transistors (HEMTs), delivering superior linearity, output power and reliability. Qorvo's forward-path amplifiers operate from 45MHz to 1.2GHz with very high output (capable of 76dBmV composite power), extremely low distortion (lower than 70dBc), and input and output return loss of -20dB (typical).

Qorvo is showcasing these products and its DOCSIS 3.1 portfolio in booth 2501 at the China Content Broadcasting Network (CCBN 2016) exhibition in Beijing, China (24-26 March).
