FN8079
Dual Band Power Amplifier
The ISL3992 is a Dual Band monolithic
GaAs Power Amplifier designed to
operate in both the ISM and U-NII
Bands as part of the 2.4/5.2GHz Worldwide IEEE802.11
a/b/g compliant radio chipset. It features two low voltage
single supply stages which cascaded deliver 21dBm (Typ)
output power for ISM, and three stages which deliver 16
dBm (Typ) for U-NII OFDM applications.
In addition, the device includes a Dual Band detector which
is accurate over a 15dB dynamic range within (±)1dB, which
can be used to implement an accurate ALC function.
The ISL3992 is housed in a 24 lead QFN package.
