Product Description
The SE2593A20 is a complete 802.
11n WLAN RF front-end module providing all the functionality of the power amplifiers, LNA, power detector, T/R switch, diplexers and associated matching.
The SE2593A20 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 Ω to simplify PCB layout and the interface to the transceiver RFIC.
The SE2593A20 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 μs.
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.
The SE2593A20 packaged in 5mm x 6mm x 1.
