ADVANCE INFORMATION
HFA3983
2.4GHz Power Amplier and Detector
The HFA3983 is a 2.4GHz monolithic
SiGe Power Amplier designed to
operate in the ISM Band. It features two
low voltage single supply stages.
Cascaded, they deliver a 18dBm (Typ)
of an 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 of dynamic range with (
±)1dB.
Therefore, an accurate ALC function can be implemented.
The HFA3983 is housed in a 28 lead exposed paddle
EPTSSOP package well suited for PCMCIA board
applications.
