Reverse path amplifiers offer maximum upstream bandwidth

The recently 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; miniaturised 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 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 GaN high-electron-mobility transistor (HEMT), which delivers superior linearity, output power and reliability. Qorvo's forward path amplifiers operate from 45MHz to 1.2GHz with very high output (capable of 76 dBmV composite power), extremely low distortion (lower than 70dBc), and excellent input and output return loss (-20 dB typical).

"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," said Kellie Chong, director, CATV and Broadband Access products for Qorvo. "Now cable operators utilising fiber to the home and Hybrid Fiber Coaxial (HFC) networks can provide higher bandwidth to meet the increasing subscriber demand for upstream and interactive content."

Qorvo will showcase these products and its DOCSIS 3.1 portfolio at the upcoming China Content Broadcasting Network (CCBN) Exhibition in Beijing, China, March 24-26^th, 2016 at booth 2501.
