This past October, the FCC began to explore opening up 1,200 megahertz of spectrum in the 6 GHz band for different types of unlicensed uses. This band is currently populated by microwave services that are used to support utilities, public safety, and wireless backhaul. Studies show that sharing this band with unlicensed operations is feasible—and can put massive amounts of new spectrum into the hands of consumers. Unlicensed innovator Claus Hetting of WI-FI NOW said, “This is without a doubt the single biggest opportunity in Wi-Fi—and probably in wireless—in a generation.” He added, “This 6 GHz spectrum boost will launch the Wi-Fi industry into a new growth trajectory.”Circuit Seed is aiming to have the best of both worlds: protect today’s incumbent users of the band while turbocharging the Wi-Fi networks and applications of the future.While this is good news for Wi-Fi, it will not work without adequate filtering to split this super wide frequency allocation into sub-bands. Ceramic filters will be able to do that, but it will be static. If an enterprise or a home wants smart frequency allocation with some ‘AI’ behind it, dynamic low loss filtering is a must.﻿Circuit Seed’s 100% digital process for analog signal processing is an ideal solution for high performance filtering with low noise and low signal loss.REMARKS OF FCC CHAIRMAN AJIT PAI AT THE 8TH ANNUAL AMERICAS SPECTRUM MANAGEMENT CONFERENCE, WASHINGTON, DC, SEPTEMBER 24, 2019

low-noise-amplifier-market

In March of 2018, Transparency Market Research published a report announcing that the worldwide low noise amplifier market is estimated to be worth US$ 7.9B by 2026.The LNA industry is fragmented with the usual group of semiconductor companies. Circuit Seed is a new platform utilising the Complementary Current injection Field Effect Transistor (CiFET) for processing analog signals using 100% digital components. This allows you to build a low noise amplifier using only two CiFETs which can be perfectly tuned to a 50 or 100 ohm antenna by adjusting the i-ratio. The power consumption is a fraction of traditional LNA devices, with a lower noise floor resulting in better range and lower SNR. The small size, less complexity and fewer BOM lowers the cost of the device. Circuit Seed is an ideal solution for low power LNAs.For more information, please contact:Lesley GentDirector Client Relations, InventionShare™lgent@InventionShare.com(613) 225-7236, Ext 131Or visit our website at www.CircuitSeed.com

Low Noise Amplifier Market

Brian Bailey’s recent article on semiengineering.com examines a number of techniques to make improvements. Circuit Seed designs with their new Complementary Current Injection Field Effect Transistor platform provides additional techniques for low power analog signal processing that generates less heat, less complexity and smaller size - reducing the cost at the same node. In addition, the designs are less sensitive to process variation and temperature beyond military specifications without correction circuitry. Circuit Seed designs are a 100% digital CMOS process and require no changes to manufacturing.For more information, please contact:Lesley GentDirector Client Relations, InventionShare™lgent@InventionShare.com(613) 225-7236, Ext 131Or visit our website at www.CircuitSeed.com﻿
