New 6 GHz Spectrum for Wi-Fi

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

Using Less Power at the Same Node

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

LOW-PROFILE ANTENNA WITH HIGH ISOLATION FOR BLUETOOTH AND WIFI COEXISTENCE

US20170033461

2017-02-02

A low-profile, planar antenna structure includes a planar dielectric substrate, a ground plane disposed on an underside of the planar dielectric substrate; a circular planar radiating element disposed on an upper side of the planar dielectric substrate; and four arc-shaped parasitic elements evenly spaced apart and surrounding the circular planar radiating element, the four-arc shaped parasitic elements and the circular planar radiating element configured to operate together as a first planar antenna, a second planar antenna, and a patch antenna. The planar antenna structure may include four notches formed in the circular planar radiating element and extending, from four respective evenly-spaced points on a circumference of the circular planar radiating element, radially inward toward a center of the circular planar radiating element.

CONTROLLING POWER CONSUMPTION IN A POWER AMPLIFIER IN A COMMUNICATION DEVICE

US9549381

2017-01-17

A method and apparatus are disclosed for controlling the power consumption of a power amplifier included in a communication device. For at least some embodiments, the power consumption may be controlled by determining an order for the data packets to be transmitted, selecting a coding scheme used to encode the data packets, and/or determining an output power level of the power amplifier. The data packet transmission order, the coding scheme, and/or the output power level may be determined, at least in part, by the temperature of the power amplifier, a quality of service associated with the data packets, a data packet length, and/or a link budget. Adjustments to the data packet transmission order, the coding scheme, and/or the output power level may be made dynamically for each data packet.

MULTIPLEXING AN RF SIGNAL WITH A CONTROL SIGNAL AND/OR A FEEDBACK SIGNAL

US20180083658

2018-03-22

A communication device includes: a transmission line; a first circuit communicatively coupled to the transmission line and configured to receive an outbound signal over the transmission line, the first circuit comprising an amplifier configured to amplify the outbound signal to form an amplified signal, the first circuit being configured to transmit a first portion of the amplified signal to an antenna element; and a second circuit communicatively coupled to the transmission line and configured to produce the outbound signal and to transmit the outbound signal over the transmission line, the second circuit further being at least one of configured to transmit a control signal for the amplifier over the transmission line or configured to receive a feedback signal, based on the amplified signal, over the transmission line such that the outbound signal and at least one of the control signal or the feedback signal concurrently share the transmission line.
