The ANADIGICS AWL9232 is a high performance InGaP HBT power amplifier, low-noise amplifier and RF switch integrated on a single IC. It is particularly applicable in consumer electronics products (e.g., cell phones, MP3 players, cameras, etc.) that integrate 802.11b/g WLAN in the 2.4 - 2.5 GHz band. Matched to 50  on all RF ports, the part requires only one choke inductor and one power supply decoupling cap off-chip.
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 802.11g and 802.11b 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 AWL9232 is biased by a single +3.8 V supply and consumes ultra-low current in the OFF mode.
The AWL9232 is manufactured using advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability and ruggedness. It is provided in a 3 x 3 x 0.55 mm ULPCC package optimized for a 50Ω system.
