SE2620T

2.4 GHz Wireless LAN/BT Front End

The SE2620T is a complete 802.11 b/g/n WLAN RF front-end module with a Bluetooth port. The device provides all the functionality of the power amplifier, power detector, harmonic filtering, switch, low noise amplifier, and associated matching. The SE2620T provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antenna, and from the antenna to the input of the transceiver, in an ultra compact form factor.

The SE2620T is designed for ease of use, with all the critical matching and harmonic filtering integrated, also offering a simple 50 Ω interface to the antenna.

The SE2620T includes a low noise amplifier to increase the receive sensitivity of embedded solutions to improve range or to overcome the insertion loss of cellular filters often included for mobile applications.

The SE2620T also includes a transmitter power detector with 20 dB of dynamic range and a digital enable control for transmitter power ramp on/off control.
