ISL3984 General Description

The ISL3984 is a 2.4GHz monolithic SiGe Power Amplifier designed to operate in the ISM Band. It features two low voltage single supply stages.

Cascaded, they deliver 18dBm (Typ) output power for the typical DSSS signal (ACPR, 1st Side Lobe < -30dBc, 2nd Side Lobe < -50dBc).

In addition, the device includes a 2.4GHz detector which is accurate over a 15dB dynamic range within (±)1dB. Therefore, an accurate ALC function can be implemented. The ISL3984 is housed in a 16 lead MLFP package well suited for PCMCIA board applications.
