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
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

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is
not implied under these conditions. Exposure to absolute ratings for extended periods of time
may adversely affect reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric performance is
guaranteed only over the conditions defined in the electrical specifications.
Note:
(1) Applied to series resistors external to V
PC
2G and V
PC
5G pins.
