Dual Band Power Amplifier

Bands. 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 ISL3990 is housed in a 24 lead QFN package.
