HFA3925
2.4GHz - 2.5GHz 250mW Power Amplifier
The Intersil 2.4GHz PRISM chip set is
a highly integrated five-chip solution for
RF modems employing Direct
Sequence Spread Spectrum (DSSS)
signaling. The HFA3925 2.4GHz-
2.5GHz, 250mW power amplifier is one of the five chips in
the PRISM chip set (see the Typical Application Diagram).
The Intersil HFA3925 is an integrated power amplifier with
transmit/receive switch in a low cost SSOP 28 plastic
package. The power amplifier delivers +27dB of gain with
high efficiency and can be operated with voltages as low as
2.7V. The power amplifier switch is fully monolithic and can
be controlled with CMOS logic levels.
The HFA3925 is ideally suited for QPSK, BPSK or other
linearly modulated systems in the 2.4GHz Industrial,
Scientific, and Medical (ISM) frequency band. It can also be
used in GFSK systems where levels of +25dBm are
required. Typical applications include Wireless Local Area
Network (WLAN) and wireless portable data collection.
REMEMBER: Always apply Negative power to the VG
pins before applying the Positive V
DD
bias. Failure to do
so may result in the destruction of the HFA3925 Power
Amplifier.
