Qorvo Boosts DOCSIS 3.1 Performance

Hybrid power doubler amplifier features GaN-on-SiC and GaAs process technologies

Qorvo has announced a power doubler amplifier, offering what it claim is the lowest power consumption and highest output capability for cable TV (CATV) DOCSIS 3.1 systems.

The RFPD3580 hybrid power doubler amplifier module features GaN on SiC and GaAs process technologies. According to the company, it provides high output capability for 45MHz-1.218GHz CATV amplifier systems, excellent linearity and superior return loss performance with robust reliability. Power consumption is 18W.

"DOCSIS 3.1 increases bandwidth to 1.218GHz, supports higher data rates and more digital content. A new DOCSIS 3.1 Hybrid Fibre Coaxial (HFC) architecture, Fibre Deep (Node+0) is designed to reduce the number of power amplifiers, but puts higher performance demands on the power doubler amplifier," said Kellie Chong, director of CATV and Broadband Access products at Qorvo. "The high performance RFPD3580 power doubler is designed to meet output requirements for this new architecture at the lowest power consumption."

Qorvo will be exhibiting its products for DOCSIS 3.1 at the SCTE 2015 Cable-Tec Expo in New Orleans, from October 14th to 16th.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
