Microchip introduces a new 5 GHz 50Ω matching WLAN front-end module for IEEE 802.11A / N / AC application

Suppliers with leading single-chip microcontrollers, mixed signals, simulation devices, and flash patented Solutions - Microchip Technology Inc. (US Micro-core Technology) announced the launch of the latest 5 GHz 50Ω matching WLAN front-end module (FEM) - SST11LF04 device Applications for mobile devices such as high data rates. The SST11LF04 device adopts an integrated compact 2.5x2.5x0.4 mm 16 pin QFN package, integrated transmitter power amplifier for 5 GHz WLAN connectivity, receiver with bypass function, low noise amplifier, and low loss SP2T antenna switch Mobile device applications that are ideal for high data rates. The SST11LF04 is small, and the 1.75% dynamic EVM adopted by MCS9-HT80 modulation and 80 MHz bandwidth can provide high linear output power of up to 16 dBm and 17 dBm, while 3.3V and 5V, while 3.3V and 5V Vcc. Linear power of 18 dBm and 19 dBm is provided for 3% EVM, respectively. This not only significantly expands the range of IEEE 802.11a WLAN systems, but also provides excellent transmission power when the highest standard 11Ac high data rate modulation mode. The receiver has a gain of 12 dB and an input (1 dB) compression level greater than -6 DBM. When the receiver is in the LNA bypass mode, the noise coefficient is 2.5 dB, and the input compression level is -6 dBm. The new 5 GHz 50Ω matched EFM allows designers to reduce board size while developing efficient design, and accelerating the pace of product listing. Due to high linear power, the new device not only implements the operation of 802.11A / N / AC mode, but also greatly improves the data rate, and the small size is characterized by the mobile device, multi-channel access point / router. As well as ideal choices for space-like applications in the set top box. Daniel Chow, vice president of Microchip RF, said: "The radio frequency power amplifier of Microchip can operate in a range of 2.4 and 5 GHz, which is reliable, high power additional efficiency, so it has a high position in the WLAN market. With the launch of SST11LF04 Microchip has brought a new compact front-end module with the same reliability in this market. The new FEM can achieve high efficiency operation, low dynamic EVM and lower receiver noise coefficients within the wide temperature range. The range of 5 GHz ultra high data rate 802.11ac system in the mobile device, multi-channel access point / router, and set-top box device is expanded. "
