Product Description
The SE2529L is a 2.4GHz, Silicon Germanium power
amplifier designed for use in the 2.4GHz ISM band for
wireless LAN and cordless telephone applications.
For wireless LAN applications, the device meets the
system requirements of IEEE802.11g and delivers
approximately +19dBm, at an EVM of 2.5%, while
achieving an adjacent channel power of better than –
26dBc @ 11MHz offset. The SE2529L meets this
performance and output power while adhering to the
FCC 15.209 restricted band requirements. For
IEEE802.11b, the SE2529L delivers approximately
+23dBm @ ACPR = -32dBc.
The SE2529L typically achieves harmonic
performance of -65dBc with the recommended
discrete integrated output match and low pass filter,
thus not requiring an expensive and larger band pass
filter.

Notes: (1) Matching networks optimized for 802.11g mode operation.
(2) With 802.11g OFDM signal at +19dBm output power.
(3) Device in standby mode by applying Vb1, Vb2 and Vb3 < 1 V.
(4) ACPR offsets are measured at stated offsets from center of channel. Measured with spectrum analyzer
settings of 100kHz (RBW) and 30kHz (VBW).
(5) EVM measured on Agilent 89611A PSA/VSA analysis system.
(6) FCC restricted bands exist at 2310-2390 MHz and 2483.5-2500 MHz.
