Product Description
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.
