SE2580L

Dual Band 802.11a/b/g/n Wireless LAN Power Amplifier

Please note: this product is being discontinued and is not recommended for new designs.

The SE2580L is a matched 802.11a/b/g/n WLAN RF Power Amplifier module providing all the functionality of the power amplifiers, match, harmonic filters and power detector.

Designed for ease of use, 5GHz RF port is matched to 50 ! to simplify PCB layout and the interface to the transceiver RFIC and switch/diplexer. The SE2580L includes a transmitter power detector for each band and transmit chain with 20 dB of dynamic range for each transmit chain. Each transmit chain has a separate 1.8V CMOS digital Enable control for transmitter power ramp on/off control. The power ramp rise/fall time is less than 0.4 µsec.

The SE2580L packaged in 3mm x 3mm x 0.9mm, Halogen free, Lead free, ROHS compliant, MSL 1 QFN package.
