2.0GHz - 2.7GHz 250mW Power Amplifier
™ The Intersil HFA3926 is an integrated
power amplifier 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 HFA3926 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 Local Loop systems.
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 HFA3926 Power Amplifier.
