Product Description The SE2520L is a power amplifier IC designed for the 2.4GHz ISM band and co mpliant with the IEEE 802.11b W LAN stand ard, providing up to + 20dBm typical output power at 3.3V with ACPR of –3 0dBc 1st lobe and –50dBc 2nd lobe, and requiring only 110mA. For 2.4GHz cordless tel ephone a pplications, th e SE2520L produces + 23dBm typical s aturated o utput power at 3.6V. The SE2520L contains a l inear analog control (0.1 t o 1.6V) for controlling DC current and output power. The SE2520 L inclu des a di gital enable c ontrol for device on/off control. Ramping is 1 µsec typical. This device is capable of operating at a dut y cycle of 100 percent.
