Description

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 HFA3983 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.
