2.4GHz 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.

As part of the Prism II WLAN chip set, the HFA3983 works
seamlessly with the chip set components to give you a highly
integrated, cost effective 11Mb/s WLAN solution in the 2.4 to
2.5GHz ISM band. The HFA3983 is fabricated in the fastest
SiGe BiCMOS process available, allowing superior RF
performance, normally found only in GaAs ICs. Cost
effective functions, normally requiring external components,
are integrated into one IC. The HFA3983 integrates the
following functions in one compact 28 pin EPTSSOP:
Two Stage, 30dB Gain RFPA,
Logarithmic power detect function (15dB Dynamic Range),
CMOS level compatible Power Up/Down function,
Single Supply, 2.7V to 3.6V Operation.
The HFA3983 contains a highly linear RFPA designed to
deliver 18dBm and meet an ACPR specification of -30dBc in
the 2.4 to 2.5GHz ISM band. The performance of this two
stage RFPA can be optimized by adjusting the bias current in
each stage with a dedicated resistor. No external positive or
negative power supplies are required to set the bias
currents. The on chip bias network provides the optimum
bias current temperature compensation when low TC
external resistors are used. To get the best performance
from the HFA3983, the output stage matching network can
be tailored using external components.
The HFA3983 power detect function provides a DC output
voltage that is proportional to the logarithm of the output
power. For an output power of 18dBm, the detector is
accurate to within a dB. The slope of the detector output
voltage is 100mV/dB over a 15dB dynamic range. A simple
application of the detector is to provide in-line monitoring of
the output power using a DC voltmeter. No longer is a power
meter or spectrum analyzer required. A more value added
application would use the HFA3861 Baseband Processor to
dynamically monitor the HFA3983 output power and to
control transmit power by adjusting the AGC of the HFA3783
IF Quadrature Modem to provide the best possible error free
data transfer rate for any given environment. Closed loop
power control is very important feature which compensates
for variability in the transmit chain (radio to radio, channel to
channel, over temperature...).
The HFA3983 power up/down feature integrates the power
down capability onto the IC and requires no external
components, thus freeing up board space and reducing
external component count and cost. When the CMOS
compatible PE (power enable) pin is driven low, the total
supply current drops to under 200µA in, typically, 230nS.
When the PE pin is driven high, the full HFA3983 output
power is available in a few hundred nanoseconds.
In summary, the HFA3983 RFPA provides a highly cost
effective solution for the PA function by integrating many
features that would require significant development time,
drive up the total bill of materials cost and consume precious
board space. It interfaces seamlessly with the other Prism II
ICs to provide a highly integrated, cost effective 11Mb/s
WLAN solution in the 2.4 to 2.5GHz ISM band.
