The SE5003L is a 5GHz power amplifier offering high linear power for wireless LAN applications. The SE5003L incorporates a power detector for closed loop monitoring and control of the output power. The SE5003L offers high integration for a simplified design, providing quicker time to market and higher application board production yield. The device integrates the input match, the inter-stage match, the output match, the power detector with 15dB of dynamic range and a 3.8GHz notch filter. Only 6 external decoupling capacitors are required to complete the design.For wireless LAN applications, the device meets the requirements of IEEE802.11a & 802.11n, and delivers approximately 23dBm of linear output power at 5V.
The SE5003L integrates the reference voltage generator. A 2.85V reference voltage on VREFis all that is required to enable or disable the power amplifier.
