PA2423U RangeChargerTM 2.4 GHz Bluetoothtm Power Amplifier IC Preliminary Applications ƒ ƒ ƒ ƒ ƒ Bluetoothtm wireless technology (Class 1) USB dongles PCMCIA, flash cards Access points 2.4 GHz cordless telephone Product Description A monolithic, high-efficiency, silicon-germanium power amplifier IC, the PA2423U is designed for 2.4 GHz wireless applications, including BluetoothTM Class1 and 2.4 GHz cordless telephone applications. It delivers +22.5 dBm output power making it capable of overcoming insertion losses of up to 2.5 dB between amplifier output and antenna input. The PA2423U provides a digital control input for controlling power up and power down modes of operation. The PA2423U operates at 3.3 V DC. At typical output power level (+22.5 dBm), the current consumption is 135 mA. The silicon/silicon-germanium structure of the PA2423U, and its exposed die-pad package, soldered to the system PCB, provide high thermal conductivity and a subsequently low junction temperature. This device is capable of operating at a duty cycle of 100 percent. The device is pin for pin compatible to the PA2423L.
