PRODUCT DESCRIPTION
The ANADIGICS AWL9924 dual band power
amplifier is a high performance InGaP HBT power
amplifier IC designed for transmit applications in
the 2.4-2.5 GHz and 4.9-5.9 GHz band. Matched to
50
Ω
at all RF inputs and outputs, the part requires
no additional RF matching components off-chip,
making the AWL9924 the world’s simplest dual band
PA IC implementation available. The PA exhibits
unparalleled linearity and efficiency for IEEE
802.11g, 802.11b and 802.11a WLAN systems
under the toughest signal configurations within
these standards.
The power detectors are temperature compensated
on chip, enabling separate single-ended output
voltages for each band with excellent accuracy over
a wide range of operating temperatures. The PA is
biased by a single +3.3 V supply and consumes
ultra-low current in the OFF mode.
The AWL9924 is manufactured using advanced
InGaP HBT technology that offers state-of-the-art
reliability, temperature stability and ruggedness. The
02/2006
IC is provided in a 4 mm x 4 mm x 0.9 mm LPCC
package optimized for a 50
Ω
system.
