MACOM To Show Latest CATV And Broadband Devices At Cable-Tec Expo'14

New suite of products aimed at deployment of DOCSIS 3.1

MACOM will show its portfolio of CATV and broadband devices at Cable-Tec Expo'14, Denver Colorado from the 23rd to the 25th September.

To keep pace with the exponential growth in data demand while using existing fibre and copper, cable networks are working toward the deployment of DOCSIS 3.1 equipment. This requires changes to the active and passive components within the infrastructure and customer premise equipment, such as higher power, linearity and bandwidth amplifiers, improved rejection filters, and a full new suite of power dividers and couplers - essentially a full refresh of the equipment toolkit.

Amongst MACOM's new products targeted at this equipment refresh are DOCSIS3.1 push-pull and power doubler GaAs solutions in SMT plastic format. These GaAs infrastructure amplifiers offer multiple system operators higher linearity and output power with extended 1.2GHz bandwidth.

Other devices include diplex filters that deliver very high isolation and return loss while simultaneously maintaining the lowest possible insertion loss. The higher power levels combined with extended frequency requirements of DOCSIS3.1 place much greater demands on the passive components in the system amplifier. Passives need to exhibit multi-octave flat response and not contribute to system distortion.

MACOM will also be showing surface mount triplex filters, which cover the 42/54, 65/85, 85/105 MHz, and 204/258 MHz bands, are MoCA 2.0 compliant and fully footprint compatible, allowing for simplified front-end designs and quicker design cycles. High performance filter technology is needed to simultaneously support next generation MoCA systems and new DOCSIS 3.1 interfaces to the core network.

The company will also be exhibiting 300 MHz reverse path single-ended, differential and variable gain amplifiers, and FTTx amplifiers developed specifically to meet Radio Frequency over Glass (RFoG) and Passive Optical Network (PON) system requirements.



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.
