Macom Adds To Expanding MMIC Portfolio

New family of amplifiers is designed for wired broadband applications

RF and microwave firm Macom has introduced five new high-performance 75Ω MMIC amplifiers. Covering 5 to 1218 MHz, they are designed specifically for DOCSIS3.1 CATV infrastructure applications requiring high gain, superior linearity and low noise figure.

All five parts cover the downstream 45 to 1218MHz cable band. Two of the five parts, MAAM-011162 and MAAM-011163, also cover the upstream band from 5 to 1218MHz.

These devices are a subset of Macom's new high-performance MMIC portfolio scheduled for launch during this year's European Microwave Week (EuMW) show in London during the first week of October.

"We're tremendously excited to be launching these new high-performance, broadband, 75Ω amplifiers targeted at next generation wired broadband infrastructure networks," said Graham Board, senior director, Multi-Market Products, at Macom. "We continue to aggressively invest in the development of new, best-in-class products that are designed to help solve our customers' most technically challenging system designs."

The MAAM-011220 is an 18.5dB Gain, high linearity, low noise figure gain block operating from 45-1218 MHz. This amplifier is delivered in an industry standard 3-lead SOT-89 plastic package and can be biased at either 8 or 5 volts depending on available voltage rails and system requirements.

The MAAM-011194, is a differential, 3 stage, VGA (Variable Gain Amplifier), delivered in a 5 x 7 mm PQFN package and operating from 45-1218 MHz. This VGA delivers 36dB gain, 2.5dB noise figure and excellent ACPR at output levels of +7 dB above Cable Labs downstream radio frequency interference (DRFI) specifications.

The MAAM-011162 is a single-ended high linearity, low noise figure amplifier covering both up and downstream bands of 5-1218MHz. This device is assembled in a 3-lead SOT-89 plastic package and provides 18 dB of flat gain in both up and down stream applications.

The MAAM-011163 is a differential amplifier covering both upstream and downstream band 5-1218 MHz. Assembled in a SOIC-8EP plastic package, this device has 19dB Gain, excellent S11 and S22 match, high linearity and 1.4 dB at noise figure at 45 MHz.

The MAAL-011136 is a broadband, ultra-low Noise figure amplifier operating from 45-1218 MHz. This device provides 20dB of flat gain, low distortion with 16dB S22 making it ideally suited as input stage for low cost fibre-to-the-X(FTTX) optical receivers and other 75 _ infrastructure applications.

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.
