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.
