Product Description
The SE2527L is a 2.4 GHz power amplifier designed
for use in the 2.4 GHz ISM band for wireless LAN
applications. The device incorporates a power
detector for closed loop monitoring of the output
power.
The SE2527L also offers a high power mode by
operating at 5 V. This provides an extra 2 dB of
improved EVM performance.
The SE2527L includes a digital enable control for
device on/off control.
The device is pin for pin compatible to SiGe’s
SE2524L, allowing both devices to share the same
application board with only a few component changes
required. This provides users with both a high and
low power solution without changing the layout.
The SE2527L temperature compensated power
detector is highly immune to mismatch at its output
with less than 1.5 dB of variation with a 2:1 mismatch.
