4GHz Power Amplifier and Detector
The HFA3983 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 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.
