5 GHz Power Amplifier with Power Detector

The SE2567L is a 5GHz power amplifier offering high linear power for wireless LAN applications. It incorporates a power detector for closed loop monitoring and control of the output power.

The SE2567L offers a high level of 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, a temperature compensated, load insensitive power detector with 15dB of dynamic range and a 3.8GHz notch filter. Two external components are required to complete the design.

For wireless LAN applications, the device meets the requirements of IEEE802.11a and delivers approximately 19dBm of linear output power.

The SE2567L integrates the reference voltage generator, allowing for a true CMOS compatible digital EN (enable) function to turn the power amplifier on and off.

Please note: SE2567L-R is being discontinued and is not recommended for new designs. The suggested replacement is SE5003L1-R1.
