Silei provides the best overall RF front-end solution for UWB systems

With the rise of the Internet of Things, UWB technology applications are facing more opportunities. Compared with other positioning technologies, UWB has many advantages such as high positioning accuracy, good security, high transmission rate, large system capacity, low power consumption, and strong anti-interference ability. The UWB radio frequency front-end solution launched by Silei Electronic Technology Co., Ltd. (referred to as "Si Lei") includes a complete set of RF chips and related product series, including:

RF front-end module(FEM)There are three series of products: SW8110, SW8112 and SW8102. As the world's first FEM series product, it provides full-band RF front-end support for UWB.

1. The SW8110 chip integrates a power amplifier (PA), low noise amplifier (LNA) and radio frequency switch (Switch). Working frequency band is 3-5GHz，It has the advantages of low noise and high output power, which improves sensitivity and reduces the working requirements for UWB transceiver.

2. The SW8112 chip integrates a power amplifier (PA), low noise amplifier (LNA), filter (HPF) and radio frequency switch (Switch). The working frequency band is 6-9GHz, with high transmit power and low noise. The internally integrated HPF provides stronger RX anti-interference ability, avoids being affected by low-frequency communication bands, and provides longer transmission distance for UWB signals.

3. The SW8102 chip integrates a low-noise amplifier (LNA) and a radio frequency switch (Switch), which is specially designed for UWB and operates in the 6-9GHz frequency band. It can achieve ultra-low noise figure, high linearity, high gain, low insertion loss and other excellent characteristics within a wide power supply voltage range of 2.8V to 3.6V, and has stronger anti-interference ability against out-of-band interference signals.

天线 (Antenna)

SW0400 and other series products:Antennas suitable for UWB 3-9GHz frequency band applications, with sizes including 2.0mmx1.2mm, 3.2mmx1.6mm, 8.0mmx6.0mm, etc., suitable for various types of product applications from wearable devices to UWB positioning base stations.

Band Pass Filter (BPF)

SW6000 and other series products:The filter chip customized for the UWB CH5 frequency band (i.e. 6.5GHz) adopts innovative IPD technology, which has low insertion loss and stronger suppression of out-of-band interference signals.

射频开关 (RF Switch)

SW1189 and other series products:Ultra-wideband SPDT switch using GPIO interface, operating frequency supports 0.7 to 10GHz. RF performance is optimized for low insertion loss and low harmonics to comply with the stringent requirements of the UWB standard.

RF power amplifier (PA)

SW8326 and other series products:Broadband power amplifier operating at 3.0-4.5GHz. While improving high output power, it can achieve broadband power drive to adapt to UWB application scenarios.

At present, the main mature applications of UWB technology are still in to B-side related industries. The core function is indoor high-precision positioning services, which has strong demand and rapid market growth.. Silicone's UWB series products have been highly recognized by 200+ industry customers and are widely used in coal mines, tunnels, justice, prisons, logistics, warehouses, ports, medical and many other industries, with cumulative product shipments exceeding 3kkpcs.

As consumer electronics giants such as Apple, NXP, and Qorvo come to an end and launch UWB main chips and hardware products, we have reason to believe that UWB technology will bring new products and experiences to consumers in the to C field.Based on the characteristics of UWB technology such as high frequency, wide bandwidth and low delay, it is expected that UWB will have broader market applications in addition to indoor positioning.Such as image and audio transmission, smart home, AR/VR, automotive electronics, etc.

Silei will continue to deepen its efforts in the field of UWB technology, continue to focus and innovate, and continue to provide customers with the best UWB RF front-end overall solution.I believe that in the future, UWB technology can become a near-field communication method that can change people's lifestyles, just like Wi-Fi and Bluetooth technology.
