(R) ISL3990 Data Sheet January 2003 FN8048 Dual Band Power Amplifier The ISL3990 is a Dual Band monolithic GaAs Power Amplifier designed to operate in both the ISM and U-NII 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.
