2.4GHz Power Amplifier and Detector
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.
