Product Description
The SE2525L is a 2.4GHz power amplifier designed
for use in the 2.4GHz ISM band for wireless LAN
applications. The device incorporates two selectable
power detectors for closed loop monitoring of the
output power.
For wireless LAN applications, the device meets the
requirements of 802.11g and delivers +19 dBm, at an
EVM of 2.7% and current of 160 mA @ 3.3 V.
The SE2525L‘s bias architecture provides for lower
current consumption at lower output power levels.
Also, the devices bias (VB) control allows for further
minor customization of the bias current for power
saving at lower output powers.
The SE2525L includes a digital enable control for
device on/off control.
The SE2525L has two selectable power detectors.
The internally coupled signal is selected by grounding
the VDETIN/DETSEL pin. This detector detects signal at
the second stage improving the accuracy under
output mismatch conditions. The second detector
uses an external RF input pin which would typically be
taken from a directional coupler output. Both
detectors are temperature compensated for minimum
component count and high accuracy. Each of these
power detectors also have selectable positive and
negative slopes for ease of use with all chipsets.
Please note this device is not recommended for
new designs. SiGe’s SE2528L is a pin for pin
compatible device and can be used in existing
SE2525L application boards with only component
value changes. Application notes are available to
assist in the change.
