PRODUCT DESCRIPTION
The ANADIGICS AWL6254 is a high performance
InGaP HBT power amplifier, low-noise amplifier, and
RF switch integrated on a single IC. It is particularly
applicable to cell phone designs that integrate
802.11b/g WLAN in the 2.4 - 2.5 GHz band. Matched
to 50  on all RF ports, the part requires no additional
RF matching components off-chip.
The AWL6254 is manufactured using advanced InGaP
HBT technology that offers state-of-the-art reliability,
temperature stability and ruggedness.It is provided in
a 3 mm x 3 mm x 0.55 mm ULPCC package optimized
for a 50  system.
The antenna port is switched between WLAN transmit,
WLAN receive, and Bluetooth paths with a low-loss
single-pole triple-throw RF switch. The transmit
path PA exhibits unparalleled linearity for both IEEE
802.11b/g/n WLAN systems under the toughest signal
configurations within these standards. The WLAN
receive path from the antenna port to receiver output
port provides a low noise, high-gain path to the system
receiver chain.
The positive slope power detector is temperature-
compensated on the chip, enabling a single-ended
output voltage with excellent accuracy over a wide
range of operating temperatures. The AWL6254 is
biased by a single +3.6 V supply and consumes ultra-
low current in the OFF mode.
