Product Description
The SE2595L is a complete 802.11n WLAN RF frontend module providing all the functionality of the power amplifiers, LNA, power detector, T/R switch, diplexers and associated matching. The SE2595L provides a complete 2.4 GHz and 5 GHz WLAN Multiple Input, Multiple Output (MIMO) 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 to simplify PCB layout and the interface to the transceiver RFIC. The SE2595L also includes a transmitter power detector for each band with 20 dB of dynamic range. The power ramp rise/fall time is less than 0.5 s. The device also provides band pass filters for both the a and b/g bands prior to the input of each 2.4 GHz and 5 GHz power amplifiers, respectively.
Features
1 Transmit and 1 receive path architecture for use as MIMO building block. All RF ports matched to 50 Integrated 2.4/5 GHz PA, 2.4/5 GHz LNA, TX Filter, T/R switches and diplexers Integrated Power Detector 19 dBm O/P Power, 802.11b, 11 Mbits, ACPR = 32 dBc 18 dBm @ 3.0 % EVM, 802.11g, 54 Mbits 16 dBm @ 3.0 % EVM, 802.11a, 54 Mbits Single supply voltage: 3.3 V 10 % Lead free, Halogen Free and RoHS compliant Thin lead free plated package, 4 mm x 6 mm x 0.9 mm, MSL 3
