射频前端 2.4/5.0GHz Dual Band WLAN/BT
The SE5501L is a complete 802.11n WLAN RF frontend module providing all the functionality of the power amplifiers, LNAs, power detector, Antenna switches, filtering and associated matching. The SE5501L provides a complete 2.4 GHz and 5 GHz WLAN RF solution from the output of the transceiver to the antennas in a compact form factor. The receive path is designed to maximize performance by providing both a low noise amplifier as well as a bypass state, for use when high power signals are being received. Designed for ease of use, all RF ports are matched to 50 Ω to simplify PCB layout and the interface to the transceiver RFIC. The SE5501L also includes a transmitter power detector for each band with 20 dB of dynamic range. The SE5501L is optimized for mobile applications with direct to battery operation
