Integrated RF Front-End Module for Wi-Fi Applications

Microchip has announced the launch of a complete integrated RF front-end module for WLAN IEEE 802.11b/g/n and Bluetooth systems.

This device is designated the SST12LF03 and it features a transmitter power amplifier, a receiver low-noise amplifier (LNA) and a low-loss antenna switch.

The SST12LF03 is Microchip’s smallest 802.11b/g/n-compliant front-end module. The RF ports on the device are impedance-matched to 50 Ohms to ensure maximum efficiency and linearity of operation.

In addition to this the module requires only two external components providing a cost effective and cheap option to implement.

With the low component count and providing the three RF functions, it takes up very little board real estate, providing real advantages for many miniaturised equipment where space is limited, and where power consumption may also be an issue. It is aimed at markets such as notebooks and other devices where both Bluetooth and Wi-Fi may be needed.

The SST12LF03 delivers 19 dBm output power at 3% EVM, using 802.11g OFDM at 54 Mbps, and it delivers 22 dBm for IEEE 802.11b operation. The device supports Wi-Fi and Bluetooth Tx/Rx, and enables simultaneous Wi-Fi and Bluetooth operation.
