PRODUCT DESCRIPTION
The ANADIGICS RFS P5022 power amplifier is a
high performance InGaP HBT power amplifier IC
designed for transmit applications in the 4.9-5.9
GHz bands. The PA exhibits unparalleled linearity
and efficiency for IEEE 802.11a WLAN systems
under the toughest signal configurations within
these standards. The PA is biased by a single +3.3V
VCC1
VCC2
supply and consumes ultra-low current in the OFF mode.
The RFS P5022 is manufactured using advanced
InGaP HBT technology that offers state-of-the-art
reliability, temperature stability and ruggedness. The
IC is provided in a 3 x 3 x 0.9mm LPCC package
optimized for a 50-Ohm system.
